Same problem from Oxford. My last good recording from the affected channels 
was made on August 19.

I'm currently running 23-fixes(25496) with nvidia driver 195.36.24 on a 
9400GT. As has already been mentioned, switching off vdpau allows the 
recordings to be watched.

mplayer appears to be able to play the recordings fine with vdpau.
