I recently converted 40 DVDs to MKV using MakeMKV. About half of those don't playback correctly in XBMC. They have an issue where the Y component plays back only on the left half of the screen. The UV components playback correctly. I was thinking that it was a problem with XBMC (as VLC plays the videos fine). However, after debugging into XBMC a little while I'm not so sure the MKV files are blameless. You can see the images and the XBMC log file output here:

Notice the discontinuity errors in the log. I'm a professional developer; I can help debug something if you can give me specifics. Thanks for your time.

MakeMKV (at least in theory) doesn't alter video stream at all - it just repackages it into another container. I would blame playback software. Please try a test:
- demux a problematic MKV with mkvextract to m2v file
- mux m2v into VOB file
- test in XBMC

IIRC you can make a VOB file with ffmpeg.

This issue was apparently caused by a bug in the nVidia 310 driver. 314 has it fixed.
