[mythtv-users] Internal player audio/video sync broken?

[Michael Jones]

It seems that the internal player's ability to maintain audio/video  
sync is broken in .21 (unless there's an option somewhere I don't know  
about).

This issue did not exist in .20.

On the following system:  All systems running FC8,

Master Backend:  Dual Xeon 2.3Ghz with Gigabit network connection, 2x  
500GB drives (one for recordings, one for videos).  Videos are stored  
in ISO format ripped with either DVDFab or DvdDecrypter/DVDShrink. 2  
Hauppauge PVR Cards (1x 150 - T1, 1x 250 - T2).  Drives are exported  
NFS, and SMB to the rest of the network.

Slave Backend/Frontend: Athlon 3000, with Gigabit network connection,  
Firewire connection to a Comcast DCT-6200 (T3), Backend drives are  
mounted NFS.

Frontend:  Pentium 3, 1Ghz with Gigabit network connection.  Backend  
drives are mounted as NFS

When playing an ISO on either the SB/FE or the FE systems the audio/ 
video sync either starts at a significant delay (about 1s) or degrades  
to that point over time.  It seems to get worse if you skip forward in  
the movie, and get a LITTLE better if you either skip backward, or  
Pause in the video.

Xine and Mplayer do not exhibit the problem. I'm currently using  
Xine.. but I'd rather use the internal player.

Playback of recordings also does not exhibit the issue.

Is this a known issue?  Is there a solution?  What additional  
information do I need to provide?


Thanks,

Michael
