Realistically, it could any combination of your system setup, a VDPAU
bug or mythtv's implementation of VDPAU.

You can get more background on preemption from:-


Is there anything on your system that might be triggering it?

Given nvidia's description, I can't see it really being a mythtv issue
in the first place. What mythtv is missing at the moment, however, is
the ability to completely re-initialise vdpau when it does happen.
That will come - just not sure when.
