Loosing audio seems to be a seperate issue. Even with the July 23rd
CVS, I can loose audio by skipping arround within the show.
I have discovered that I can consitantly cause it to loose audio by
"Increasing the playback speed" (i.e. pressing `U'), and then pressing
"play". After pressing "play", the video plays fine, but is completely
silent. This is true both with AC3 from a HD-2000 file and the mpeg
audio from a PVR-x50 file.
Can you send me your patch for the "keyframe" problem, so I can try
applying it to version of the CVS after July 23rd? I would like to
eliminate that problem to help narrow down when the "video freeze"
problem was introduced. TIA.
