(still on bf36dc50). Note that I did not compile XBMC between these runs,
I simply swapped the ffmpeg libs and rebooted.

different bug than what I thought so far. The difference in the XBMC
source code would be that the new API uses a "hwaccel" and the
"h264/vc1/etc. decoder while the new API was based on specific decoders
h264_vdpau, vc1_vdpau etc.

Or actually something like:
{{{
./configure --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64
--enable-shared --disable-static --enable-gpl --enable-avresample
--enable-version3 --enable-nonfree --disable-doc --enable-gnutls --enable-
libmp3lame --enable-libaacplus --enable-libtheora --enable-libx264
--enable-libxvid --enable-libass --enable-libbluray --enable-libopus
--enable-librtmp --enable-libspeex --enable-libvorbis --cpu=atom
}}}
If there really is a problem with the dev's, please report it!
