Hi,

This sounds like the same problem I reported in #11377 
(http://code.mythtv.org/trac/ticket/11377).

I submitted a clip to NVidia who confirmed they could reproduce the 
problem in MythTV but not in mplayer.  I've not heard anything more 
since, unfortunately, so I don't know whether it is purely a VDPAU 
problem (and mplayer is not using some feature that MythTV is) or not.

Richard.
