[mythtv-users] Audio out of sync when playing back from DVD iso

The setup is:


   2.8GHz Hyperthreaded w/4GB ram
   2 750GB SATA hardrives
   nVidia 6200
   HDHomeRun tuner

   OpenSuse 10.3 i586
   mythtv RPMs 0.21 from Packman

I have used ddrescue to get an ISO image from a couple of my DVDs on to 
my hard drive.  MythDVD recognizes it and presents menus, etc.  I start 
playing one of the DVDs from the image and the sound is out of sync. 
I'm using mythtv to playback the DVD, not mplayer.

Frontend and backend are on the same machine.  The machine is not 
recording when I try to play back a DVD from an iso image so, the 
machine is idle apart from the playback.  I have an unencrypted DVD 
which seems to play fine, the encrypted DVD image I have does not.  The 
video quality on the unencrypted DVD is also lower quality IMO.

MythTV plays recorded HD and SD content just find and in sync, the DVDs 
are not playing right.  Any suggestions?
