Do you use USB tuner cards?  Is the tuner perfect without a single 
imperfection in the stream?

I have a problem USB tuner and reverted to a PCI one temporarily.  What 
I noticed is that VDPAU massively exagerates the effect of any glitches 
in the stream.  Playing the same thing back with a software decoder and 
I see perhaps a square of breakup, with VDPAU I see half the screen tear 
and glitch.

Possibly the root cause for you is the tuner and not the decoder?

Note in my case I haven't tracked down the issue with my usb stick.  
femon is showing zero errors in the DVB frontend, mplayer is playing 
back the recorded stream very nicely, but mythtv is showing regular 
(every few secs) glitches.  Seems like a USB issue because the PCI card 
is perfect.  However, it may be a partial interaction with mythtv 
because mplayer is fine?

Good luck
