Hi-yas,

I upgraded my mythbox today to try to fix some other problems we were 
experiencing.
I did a 'do-release-upgrade' to upgrade 12.04 to 14.04.

Everything went mostly smoothly, looking perfect in face.

But now it *looks* like we're getting system lockups playing back video.
(it may be locking up independant of what it's doing, but I doubt it).
I'm not 100% sure what's up, but there's video corruption, black bars, 
red-screens, etc. etc. then a few seconds later the box locks up.
It does run OK for about 20 minutes sometimes.

Worked perfectly before the update.

To try to fix the problem, I've removed (with purge) the nvidia drivers, and 
re-installed nvidia_331_updates.
But this has made zero difference.

I tried looking for kernel panic debug messages or suchlike, but alas found 
nothing... where would I find these?

Any advice very much appreciated.

Maybe I should test it without vdpau?  Worth a shot?

thanks,
-kt
