This is weird. I've backported relevant parts of VLC 1.1 code to 1.0 and
VAAPI works fine for me, though libva/vdpau-vaapi i'm using are: 0.2.9
with patches from Gwenole and 0.3.1 respectively.

Actually, few weeks ago I've built 1.1 with newest (at the time) versions
of those libraries and they also seemed to work fine.

I will do more testing today, though i only have some .m2ts and .mkv files
with H264, nothing really fancy.
