Hi,

I am running mythtv from trunk with a nvidia 8400GS card and VDPAU enabled.  On certain movies, using green latern for this discussion, mythfrontend will lockup (ie screen goes all wacky and it's none responsive, I have to alt-tab-F1 to another terminal and kill everything).  

ffmpeg shows:

I figure this is a bug...  But I wanted to check with other smart people first...
