Well, I can tell you I didn't pick the model, but my family seemingly believes on: schedule for the day > choosing the ONE upgrade they'll buy in years wisely. I even gave them a list of models that (according to the manufacturer's specs page) are 120 Hz-capable, but they bought another.

I actually saw that bit on the manual, it just struck me as flat out dumb that there wasn't a way to get a 120 Hz signal on a TV capable of showing 120 fps. Sorry if I give you the impression of someone stupid by asking a way to not get a huge disappointment each time I see the only TV upgrade I'll see in years. I may whine a LOT about import taxes, but that same TV you get for 800 dollars? Here it's over 1200. And of course, a 3rd world budget doesn't allow upgrading home electronics very often.
Damnable shady marketing and "120 Hz" TV's that can't receive a 120 Hz signal.

Edit:
So I made some further research on the TV's shown in the site of the store where we bought the TV.
Each and every one of the at least eight different 120 Hz (or even higher) TV's from which I've been able to track down their manual, actually can only take up to a 60 Hz signal.
There's only three I haven't been able to find any manual online or even the manufacturer's model page, which leads me to suspect they're "Argentina only" models, needless to say these aren't very promising on actually being able to receive a 120 Hz signal. They are:
Philips PFL4508/77
Sony KDL-40R485
Philips PFL3508G/77

I... don't say this very often, but I think I have little choice but to give up. On a true 120 Hz display that is, as it appears there's literally no such thing where I live. Now THAT sucks.

What the title says, pretty much. In a nutshell, we've finally upgraded our TV at home, I saw a chance, took it, and insisted it HAD to be 120 Hz. Unfortunately 120 Hz screens are a rarity where I live, thanks to our wonderful (/sarcasm) import laws and my government's policy of systematically screwing over anyone who tries bringing anything from outside the country. It also appears that due to the locals' severely inefficient way of handling technical specifications, the best way to ensure the TV you're buying has 120 Hz is getting one with 3D support.
So we got a LG 42LA6200 (official specs page: http://www.lg.com/us/tvs/lg-42LA6200-led-tv )

I promptly connected my computer, which I'm fairly confident it's up to spec (i5 3570, GTX 650 Ti Boost, 2x8GB RAM @ 1600, Win7 64 bit) to the TV, but to my disappointment, I seem to be unable to set the refresh rate any higher than 60 Hz.
Is there anything I can do to get a screen refresh rate of 120 Hz?

I've already bought a new HDMI cable that claims to be 1.4b which I'm using right now, but thanks yet again to my country's import laws, it's a generic brand cable and I can't be sure it actually IS 1.4b, since the cable itself doesn't say "1.4" anywhere on it.
I could simply make a new unsupported resolution from the Nvidia control panel set to 1080p @ 120 Hz, but I'd rather be absolutely certain I won't blow up anything (mostly and more importantly the TV) before I do that.

Any help would be amply appreciated smile

It would be nice if you could tell me your settings for the 720p and 480, esp. for anime

Actually I use the exact same setting (for anime) on each resolution.
I'll try different Motion vector settings though (if my cpu alone can take it), more fluid = better. That's the idea of SVP after all.

some 1080 movies and my desktop cant play it properly

CPU:  AMD Phenom II X4 965 @3400 MHz [4 threads]
GPU:  AMD/ATI Radeon HD 6900 [ver.1016.4]

You really should be able to play morbid bitrate 1080p blu ray rips on that. I have a Phenom II 955 (4 threads @3.2 Ghz) with a powerful yet unsupported card (HD 4890 sad) and I can play 1080p flawlessly with *checks* 65-75% cpu load. And on cpu only that is.
What settings (and renderer) are you using? I'm using Video Mixing Renderer 9 (renderless) and these settings for near-perfect 1080p anime-watching goodness:

I had (a different) problem with 5.1 audio, but the solution I used can apply as well. I posted a thread with a tutorial here: http://www.svp-team.com/forum/viewtopic.php?id=1097 In your case, just set the Output format in the AC3 filter control panel to either "3/2+SW 5.1 channels" or "AS IS (no change)". Keep in mind that if you set it to 5.1 you'll have to change it back to stereo to have good audio on headphones.

PS/edit: VLC in particular is incompatible with SVP, but other players should work fine given an appropriate setup. I like Media Player Classic so I keep the SVP default on that.

Most likely it's some audio misconfiguration (at least your speakers are really bad). What are your current audio settings on Media Player Classic? Do you have any specific setup on ffdshow audio?

I recently noticed some files randomly skipped when played with MPC since I installed SVP. It happened very often (usually about 4-5 times per minute) making movies unwatchable.
If the performance graphs were opened it looked like this:
http://img703.imageshack.us/img703/2856/jumpyplaybackgraph.png

What's interesting is that SVP had nothing to do with this problem, as I tried the same video with SVP disabled and the problem persisted, yet it was still reflected in the graph for reasons unknown to me:
http://imageshack.us/a/img827/9914/jumpyplaybacksvpoff.png

After days of trying every setting looking what could be the cause, I found a common factor. Surround (5.1) audio. I was using headphones, so the audio had to be downmixed to stereo, and somewhere in that process the video got jumpy.
It would seem that by default, the "System default" audio renderer selected in MPC was doing the downmixing, so I had to find an alternative. The solution I came up with was:
First, I changed the Renderer to my audio card:
http://imageshack.us/a/img33/6430/audiorendererchange.png

Then I went to the External Filters option, clicked "Add Filter..." and selected AC3Filter
http://imageshack.us/a/img832/3659/addac3.png

Then, double click it on the External Filters list, go to the System tab and configure it to be preferred over other decoders
http://imageshack.us/a/img827/1148/preferac3.png

Then, close the AC3 panel, the Options menu and MPC, then launch a video with 5.1 audio. All that's left is to go again to the AC3 config and set its Output format to Stereo (this can be done in the previous step though tongue).
http://imageshack.us/a/img10/2586/surroundtostereo.png

While I was on it, I set it to decode at the highest audio quality (rate & format) my audio card can process. Done! 5.1 to stereo without jumpyness!
Please note that the highest quality for different audio cards vary, and integrated motherboard audio cards are overall less powerful. Be careful when configuring this and mostly, don't do it while playing a file, even less at high volume!

Hopefully this can be of some help to someone. It is certainly better than a dummy post saying "my video skips and I'm not giving any technical info i want a fix help me plz" lol

P.S.: I keep getting the feeling I forgot a detail in the instructions. If someone spots it, do tell me please.

Thanks smile
For some reason I didn't even consider subtitles as a cause for the problem, so I didn't disable them to confirm. I will edit the first post title to more accurately tell what causes this issue.

Edit:
For science! I tried changing the renderer in MPC output settings as well as subtitles settings. I got some interesting results.
I quickly found out that I could get stable framerate (almost, it dropped to 59, 58 fps a couple times) on these troublesome dynamic subtitles by using these settings:
http://imageshack.us/a/img823/1244/subtitlesettings1.png

Instead of the default ones:
http://imageshack.us/a/img577/2819/subtitlesettings2.png

The texture size at 720p did not represent a noticeable loss on fullscreen (and I have a 1080p display).
I could not find a fix to the high memory usage, but I did notice that different output renderers had slightly different memory performance. I did not make enough runs to call this a truly reliable "scientific" test, but (always on a 720p window):
-VMR-9 (renderless) peaks to about 900 Mb.
-EVR Custom Presenter peaks barely over 900 Mb, and not always gets over 900.
-Haali has the lowest memory usage of all, doesn't reach 600 Mb, but it also had flashing subtitles on my settings sad
-madVR seems to hit a "limit" at 910 Mb, but always reaches that level.

Something noteworthy: Disabling "Allow animation when buffering" on MPC Subtitles options allows to free up memory much quicker.
I recalled one of these had a higher memory usage so I played the ending with all renderers again but with subtitle textures set to 1920x1080. It would seem Haali uses a lot more memory (even when the window size was 1280x720) with higher subtitle textures. I tried getting to an optimal setting with the Haali renderer with no avail, as it requires "Allow animation when buffering" enabled so subtitles are constantly visible.

Using EVR Custom Presenter and the subtitle settings I posted before I got to this performance graph and a stable framerate all along (on a 1280x720 window). Maximum memory usage was 906 Mb.

Yes, I played the same bit of video like 20 times in a row, that music is going to resonate in my head for days.

I just went ahead and uploaded it while I was out for a while.

It's a whole episode. I didn't check closely but apparently the whole thing plays ok, with the exception of the ending credits (starting around 22:20) that refuse to play at 60 fps.

After some testing, I have determined it's the particular encoding of some particular episodes, plus my 1.5Tb Seagate hard drive (ST31500341AS) acting up as I moved the videos to my other drive, a 640Gb WD (WD6400AAKS-00E4A0) and things performed slightly... less bad.

Putting it on clearer terms: I have this video sequence https://www.youtube.com/watch?v=tUS7gSv2ZxE
On "encoding A" and "encoding B".
Encoding A performs excellently on both hard drives.
Encoding B has very poor performance on Seagate hard drive, slightly less bad on WD hard drive.

My internet connection isn not exactly fast for uploads, so uploading a ~300Mb video file for the final 1:30 minutes isn not exactly profitable, and if I re-encoded the troublesome bit and sent it I would lose the particular encoding that triggers this issue.
As I obtained the video file on a "t0rr3nt" site, I'm not entirely sure if I'm allowed to post a such a link here, in addition to the fact I have yet to find a "Forum Rules" section xP
I would PM you but I have found no way of doing so either so... what to do?

I will try to upload the video later today, though.

Well, just for the sake of science, I watched another episode of that particular anime where I experienced the "memory leak" (if it's fit to call it so).
I got a sign at the same spot where I got the memory leak ones before, I took a screenshot of it but I was so dumb of copying some text before pasting it on an image editor.
If my memory serves me right, it was something about an error when generating an errorlog (oh, the irony).
Afterwards I noticed the ending on that anime is rather merciless on motion interpolation. Here's a link to said ED (Youtube link). Up to 0:57, it's like it was designed to not be "SVP'd". They'll have to try harder >:3
SVP takes it like a boss and generates not only the frames needed for 60 fps but also no artifacts cool (well, no artifacts that I could see)
Then I did a quick test on that ending and watched it (on 720p) with the performance graphs running.
http://imageshack.us/a/img542/1307/performancegraphsanimee.png
Then, I did the same but on fullscreen (I have a 1080p display). That's when MPC's memory usage hit over 1100Mb, and in less than 1 minute! It peaks specifically on the part with a girl with a black dress. It's like a crazy motion interpolation test  hmm 
http://imageshack.us/a/img254/1307/performancegraphsanimee.png
The 400-something Mb is me being a fool and not noticing MPC continues to use memory while on pause.
I think I should note that while I wasn't exactly noticeable due to a lack of a clear movement pattern, the first half of the video had very unstable framerates (even below 24) according to Fraps.

What filter are you using for subtitles?

Well, this is embarrassing. I have no idea. Overall, video decoding isn't my specialty, I usually fiddle with player settings until I get it working as I want to.

If I understood Media Player Classic's tooltip's correctly, I'm using its internal subtitle renderer, and EVR Custom Pres. for Direct Show video.
I think however, that the MemoryLeaksDetails mod.zip fixed the issue, as I played both the proportionally biggest video I have (1.22Gb for 24 min! 1080p + 3 audio streams, 2 of them in flac lol) and a 51 min 720p video with no issues. Both had ASS (talk about an unlucky acronym) lossless compression subtitles.
Memory usage for Media Player Classic didn't even reach 600 Mb when playing the 1080p video @ 60fps.

P.S.: I should note that I've set all 4 profiles to the same settings.

Originally posted to report memory usage peaking, dynamic subtitles confirmed as the cause.
This bug seems to have been fixed on SVP 3.1.3! big_smile

==============
Original Post below
==============
But first, bear with me while I attempt to put in words how grateful I am for this stunningly amazing piece of software. If you ask me, SVP is a prime example of hardworking independent developers pulling out freeware with capabilities commercial software can't even dream of.
Why such a difference? Because software such as SVP is intended primarily to work, not to sell. And that's why I love the thing. It's efficient, unlike most of everything you see out there.
What really moves me is all the effort the SVP developers put into it. I'm not exactly trained on coding, I can barely do some kiddie-level scripting, but just using the UI, reading the documentation and logs, and most importantly: The results. Steady 60 fps on 720p and just 30% cpu load?! YES PLEASE.

Of course, no software is perfect. Yesterday, I got a warning sign while watching an anime episode. I didn't take note of what it said, mostly because of the shock I think, it was the first unexpected issue I ever had with SVP after all.
Fortunately the same message is on the attached errorlog, apparently it said this: "Error: Warning: there's a memory leak in the video player: 1170 MB
To prevent the closing of the player due to lack of memory a script restarted improve smoothness."
Gotta love "good guy SVP" xD
"Detects memory leak. Fixes, warns user and doesn't even break playback."

My 1280x720@24 profile is as follows:
Frames interpolation mode: "2m" (min artifacts)
SVP shader: 2. Sharp (for anime)
Motion vectors interpolation mode (grayed out for some reason): Bilinear
Target frame rate: To screen refresh rate (default)
Motion vectors grid: 32 px. Large 0
Decrease grid step: By two with global refinement
Search radius: Small and fast
Motion vectors precision: Two pixels
Wide search: Disable
Artifacts masking: Strongest
Processing of scene changes: Repeat frame (default)
Decrease frame size: Disable (default)
btw, I've extensively tested these settings and I dare to say it works about perfectly with not just anime, but with live action videos as well.

My system specs:
AMD Phenom II 955 (x4 @ 3.2 Ghz)
Gigabyte 870A-USB3
Sapphire Radeon HD 4890 Vapor-X
2x G-Skill F3-12800CL8-2GBTD (2x2Gb 1333Mhz)

Additionally, the video-related MediaInfo on the anime episode I was watching during the memory leak. Not sure if it'll be of any help but, best to be sure.
