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

 > It would be great if you could verify this because it would indicate a
 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.

 of the one you compiled against, using a newer one may be ok (bugs are of
 course possible), ideally you would recompile to get valid results.

 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!
