Oh I see I forgot to say what I got that from, I got it from Process Hacker 2. I have a GTX 680. No, I didn't try the old driver. I've played games recently without any problems with my graphics card.

I think I might have fixed the problem, I just watched a 40 minute video with SVP without a single freeze. All I did was turn off Frame Limiter in the Nvidia drivers that I had set to 60FPS, I've had this set to 60FPS without problems before tho.

Yep, what the title says. At random intervals the video freezes for a duration that varies, can be 2 seconds or 8. Audio continues. While this issue is not limited to SVP, it might be the easiest to troubleshoot, the same thing happens to Firefox and Chrome. I run MPC-HC with LAV, madVR, ffdshow and SVP. This issue very rarely happens in MPC-HC if SVP is disabled, it does still happen in Firefox.

It started a few days ago, around the time when I updated my graphics drivers. A new WHQL driver came out a few days after that so I made sure to do a clean install, the issue remains. I've used LatencyMon to see if the driver had a long execution time but it didn't, and nothing else freezes that I've noticed. I've analyzed the wait chain(?) of the most CPU intensive of the 2 avisynth threads in the MPC-HC process at the time of the freezes and it says:

Thread is waiting (alertable) for:
Handle 0x661084: (error querying handle)

The handle number changes, I've seen it be 0x1 and 0x7something. CPU usage at the time of freezes is low, as if it's waiting for something before continuing. When the freeze stop, the video fast forwards to catch up with the audio. Here is a picture of the performance graph:

I must add that the image above shows a rare occasion when several freezes happened in a small time frame, they are usually further apart than this. While I don't think it will help, here is the SVP log:
