The VAAPI code in master was tested using an Intel Carkdale chipset
running Ubuntu Lucid (using, from memory, the xorg-edgers bleeding
edge X updates). It was stable. That same box has now been upgraded to
a stock Natty install and VAAPI is less than stable - with frequent
crashes. I've not looked into it so can't be sure whether it's a
driver issue or further problems with the MythTV code.

As has already been mentioned, VAAPI is less feature rich than VDPAU
(limited deinterlacer selection - if you can get it to work), no
picture controls (on Intel), no VC1 support (on that chipset/driver
version at least) and probably a few other things I've forgotten.

AMD support is another issue entirely. The last time I tried to get
the fglrx driver installed on one of my systems, I completely trashed
it. Haven't tried since:) You may want to have a look at:-
