OK, I tried messing with the Playback profiles and I think I found 
success.  I had it set to Slim from 0.21.  Since I have an nVidia 9400GS 
card and the nVidia 185 .18.31 driver that should support VDPAU, I 
changed the Playback profile to VDPAU High and played the recording.  
Played fine.  No issues with video or audio (everything in sync).

For now I'm going to leave it like this.  Does anyone else have any 
reasons why this wouldn't be acceptable?
