One thing I did notice when playing these movies is that even though VDADecoder was enabled, the CPU usage was rather high - hovering around between 90% and 140% (dual-core, I guess 200% is maximum); and it seemed to be higher in the movies where it was showing the problem, but still high even when managing OK. Probably a sign that VDADecoder isn't *finished* yet; but I think we knew that already. :-)

Type 'o' to bring up the decoder OSD. Then look for vda-xxx. That will tell you if VDADecoder is actually being used as the decoder.

EDIT: You might also use MediaInfo to qualify what's different about the files that work vs the ones that have problems.
