Linus,

Can you give a little more detail about video not working?  Video
accel should work fine with the current versions of libva/intel-driver
available in Fedora 19 - assuming that's what you're using.  I am
running that on my MacBook Air 2013 and  HSW based Asus quad core i7
desktop.   A quick way to exercise the decoders once you install
libva/intel-driver is to use VLC enabling GPU acceleration in
preferences.
