Hello,

I run the last version of VLC media player, on my WinXP laptop (or on another Win7 laptop), and I've some problem to play MKV file: freeze, lag, pixelation...
Do I have to apply some special settings to VLC media player to watch MKV file correctly?

Thanks,
Chris

I have the same issue and have read about downgrading to older versions though some people have said that this isn't necessarily a permanent fix to the issue as the problem may be with the video files. I have this with MP4 files as well.

Try another video output module:

And/or disable/enable GPU acceleration:

And/or adjust FFmpeg threads:

You can also try to enable or disable some video options such as Overlay and/or Hardware YUV -> RGB conversions.
