The situation with VDPAU and timestretch has greatly improved since we
talked about this last.  Last time, the stutter happened as soon as I
turned timestretch on.  That is no longer the case.  It actually works
"in general".

However, after a while, a *minor* stutter will start up.  My
perception is, that this happens after a commercial skip or after I
jump around (3 minutes, 10 minutes, etc) in the show.  I am guessing
that something is not getting reset in a situation like that.  Once
the stutter happens, I have to reboot to get it to go away.

I will experiment some more with it, and see if I can narrow down the trigger.
