I've been noticing this since I started putting my Doctor Who blurays into XBMC, but they all seem to drop a lot of frames.

This is from one of the episodes:


855 drops at only one minute into the episode if I'm reading that right. DXVA2 is on.

It's been a month or so since I pulled it on so I can't remember exactly how I did it, but I used Ripbot264 to transcode it because Handbrake doesn't work with VC1 streams. It seems as though Ripbot put it into an AVC stream and also made it progressive instead of interlaced apparently. This is what Media Player Classic has to say about it. Note that MPC does not drop any of the frames, it plays back smoothly:

Am I missing something fundamental here? I'm fairly new to the whole pulling stuff off blurays and into the library and my BBC shows have been giving me hell. So far I have 3 episodes like this, all Doctor Who, all bluray, all originally VC1 streams. Tips, tricks? All are appreciated. Thanks for your time!

Also, if I have omitted anything critical, let me know and I'll add that.

Debug log where I started playing the episode for about 30 seconds:
