Comment (by peper03@…):

 Are you getting the same 'Video is X.Y frames ahead of audio, doubling
 video frame interval to slow down.' error messages?  What playback
 performance are you getting (std dev etc.)?

 The playback seemed to be fine on the DVDs I tested but I'll try it again
 on a larger sample.

 Since the conditions for whether to buffer a video frame or not have been
 relaxed, I would expect (if anything) too many frames to be buffered.
 There are several other places in the code where IsInDiscMenuOrStillFrame
 is called but none that appeared to be related to the buffering.

 Maybe you could also try the patch I just attached.  It'll create a lot of
 noise but shows whether the storedpackets buffer keeps running empty or
 not (when storevideoframes==1 and count==0).
