Comment(by mab893 at hotmail.com):

 Here is an example of a video with the problem (~22mb):
 http://home.comcast.net/~martin-glass/test.ts

 It occurs a few seconds into the clip, and appears to be because the
 PICTURE_START_CODE start_code isn't encountered before the slices
 (SLICE_MIN_START_CODE-SLICE_MAX_START_CODE) are processed. This causes the
 decoder not to be initialized for this context, and for some reason the
 buffer is never unlocked after the slices are completed (although the
 frame does make it to release_avf_buffer_xvmc) ...
