Hey guys, I'm having a really odd problem and I can't seem to solve it myself...
Basically here's what happens, I'm using the CCCP codec pack with MPC and when I play any video everything works fine until I try to skip to any point in the video (i.e. I want to skip the intro of the show I'm watching so I skip 1 minute into the video), at this point the video becomes extremely choppy while the sound remains fine. This happens to any media player I try to use except (for some odd reason) Windows Media Player works fine :mad:...

Any ideas?

Thanks in advance,
-ATH

What's your GPU? What version of Windows? What type of files are affected?

Any video files are affected (.avi .mpg .mkv... etc.)

There's a weird stuttering bug with the latest nVidia ForceWare drivers + EVR-CP? that's been going around. Are you on a recent Forceware?

You can try first a reset of MPC-HC settings, try turn alternate vsync on or off (make sure that the basic v-sync option is always enabled) . If that fails, try change the video renderer and finally possibly change your display drivers if necessary.

Lol, I just went to nVidia's site to check the latest drivers and the newest one has the following fix in it: "Fixes a video playback issue in Media Player Classic."
Downloading it now, I'll let you know if that fixes it.

P.S. Thanks for the help so far =).

***Edit: Nope it seems like it just fixed some unrelated crash that I personally never experienced... I'll try the other suggestions for now.

***Edit 2: I tried different combinations of VSync settings, which didn't work, I then tried different combinations of renderers under Options>Playback>Output and it worked it seems my stuttering problem is happening when the renderer is set to "EVR Custom Pres. **".

Any idea why that renderer is problematic? I currently have it set to "EVR (Vista/.Net3)", do you have any suggestions of which renderer I should use, i.e. which is better, what's the difference?

That issue is a DXVA issue, not the stuttering issue, last I heard.

You can also try use the latest CCCP beta which is at 1871.

You need to use GeForce 196.21 WHQL drivers.

http://www.nvidia.com/object/win7_winvista_64bit_196.21_whql.html

And use the latest MPC-HC build, not the outdated stuff in CCCP. Latest is SVN 1875 atm, but it's regularly updated.

http://www.xvidvideo.ru/media-player-classic-home-cinema-x86-x64/

I'm using 197.45 WHQL at the moment which is the latest stable release, is there a reason to stick with the older set of drivers? I thought the newer ones provided better optimization and performance increase overall (before anyone mentions it, I'm aware of the past 197.75 build situation :p).

Also is there a reason that CCCP is so outdated? Is the project no longer supported?

***Edit: Is K-Lite pack any good compared to CCCP?

There was a beta release two days ago.

Basically, the question you should ask is: Am I experiencing any media playback issues with CCCP? If so, what are they?

...and it's already known that your video stuttering issues are an nVidia driver issue.

Regarding CCCP; If it's not broken, don't fix it.

I having the same studdering issues with MPC-HC. For me this problem goes away if I switch ffdshow h264 decoder from ffmpeg-mt to libavcodec. Has anyone else tried this?
