H.264 decoding is only supported on Intel HD Graphics at this time. IIRC, 
I have a patch for run-time detecting that (instead of the assert) hanging 
somewhere at home. I will check this out. This simply makes sure to not 
report H.264 on plain old G45 hardware.

I don't know if Intel still plan to support older G45 chipsets. My 
opinion, would be to focus on partial VP8 acceleration or VC-1 support on 
Intel HD Graphics, which is current HW.
