I have installed Mythtv 0.21-fixes on a new macbook unibody, with a
9400GM chipset...

I'm quite impressed by the GPU. Speed is reported at 450MHz only (so
faster than the 8400gs above)...
It does MPEG2, H264 and VC-1 in hardware, and can handle all
deinterlacer for non HD video and up to Advanced 1X and Temporal 1X
when watching 1080i content...

So just like the 9400GT card I mentioned above...

Can't wait to try with gigabyte motherboard with the 9400 running at 580Mhz...

The 9400GM in the macbook runs at the same speed as the nvidia 9300
chipset found in the Asus or MSI motherboard... So it will give an
indication on how those boards would perform with VDPAU ..
