I am having a problem playing back recorded (via HDPVR) shows.  There is 
intermittent dropping out of audio and perhaps a brief skip in the video 
then playback continues.  The log is filled with hundreds of entries like

I researched this, and it seems to be related to VDPAU somehow, but I can't find any consistent recommendation for a fix.  I have the latest NVIDIA drivers installed.  Anyone have idea about how to address this?
