I don't think one really need madVR's "smooth motion" together with SVP. It makes sense watching 23.976 on 60 screen but not in our case - e.g. 59.94 to 60.02.
Probably it's better to do true interpolation up to 60.02 - see "Target frame rate" -> "Force the exact value" in the latest SVP build.
But I'm personally good with just 59.94 
does it happens on the same file every time?
what if press "retry?"
Works for me.
You probably need to update cookies in SVPtube's authentication data.
they'd better integrate mpv engine
SVPtube menu -> Video player -> Choose application... -> mpc-hc.exe, etc...

It won't run 2x4K (4000*4000) stereo VR 
SVP works via Avisynth.
If you "disable it in ffdshow configuration by unticking it" then SVP is NOT working.
If video is lagging with SVP on then you probably should adjust something.
clCreateContext() error 999 - not documented, seems like it's NVidia-only error code meaning nothing but "unknown error"
you probably need to update / revert / reinstall / etc video drivers

mpv process creates /tmp/mpvsocket file
if you kill mpv the file will gone, obviously
nope
vorpX is a 3D-driver for DirectX9-11
it's like virtual screen
the very same MPC-HC renders smoothed video on that virtual screen
Tested so far:
1. Whirligig Media Player - howto
Pros:
- great VR controls, supports Oculus Touch
- plays at true 90 Hz mode
Cons:
- doesn't support custom DirectShow filter chain, so using "ffdshow video decoder" as a decoder is the only option compatible with SVP
- can't handle frame size change on-the-fly i.e. SVP's frame crop and outer lighting
2. vorpX "Cinema mode"
Pros:
- uses common video players - MPC-HC, mpv, VLC, ... - to render the video
- has some VR-specific image quality controls (probably useless (?))
Cons:
- limits video renderer to 45 Hz
- doesn't work (?) with madVR
- expensive, BUT it can "cast" desktop games too

If true then num/den define absolute frame rate value instead of multiplier for source frame rate.

on Windows is can actually measure the value... but not on Linux

it's limited to 0.001
60.0/23.976 = 2.5025
358/143 = 2.50349
2.50349-2.5025 < 0.001
probably there's a room for improvement here
> For some strange reason when these value are missing in tube.cfg the error is caused
the error is when some cfg options are missing which normally happens at the first run only
=====================
smooth.rate.num=60;
smooth.rate.den=1;
smooth.rate.abs=true;
it definitely works but it won't change numbers displayed in log and OSD
> target/tolerance at 0
Are you sure your screen is exactly 60 Hz? You can also manually set "fixed 60 fps" in the video profile
12:48:20.543 []: Media: video 1920x1080 [PAR 1.000] at 23.976 fps [variable]
...
12:48:20.635 []: Playback [1ac0734]: playing at 60.0238 [23.976 *358/143]
> How do I turn off performance quick estimation at the start of SVP?
Why?
you can't fix it yourself
will be fixed in the next build
> Does madVR and SVP coalesce without any hiccups?
yep
turn off "svplight" extension if you're not using it
will be fixed in the next build
not "external filters" section but
playback -> output -> video renderer
- choose madVR as a video renderer in MPC-HC's options
- find the icon in system tray OR via right-click in MPC-HC window -> Filters menu
you don't need to reinstall it
you can install madVR via Utilities -> Additional programs and features
When you turn on GPU acceleration the actual settings change to higher values - this's why you may not see lower CPU usage.
You can easily adjust CPU usage with the "performance-quality" slider.
> how can i force more usage of my gpu?
set NGU "very high quality" in madVR
More likely it's about not stable source fps value and/or frame drops and/or possibly interlaced contents on some channels
- What do you see in SVP's log?
- Take a look at source fps value in ffdshow properties -> Info tab -> "Movie FPS" value
- Set "Movie x2" mode in profile options
It's not easy to reproduce the problem on my rig 
I'll probably prepare a special debug version that will write an excessive log, but maybe it's better to move to email at this point.
