The 965 media support is pure software, so it should be able to manage
H.264 (not that I've looked into this at all, but, I *think* it should

We haven't published the hardware docs for other people to do the work,
so right now it's on our internal list of projects to get worked on this

1080i should work fine without hardware iDCT with any kind of reasonable
processor, so the lack of GPU-assist here shouldn't keep you from using
the box. If you're planning on driving component video on the output, be
aware that we also haven't gotten SDVO TV out cards working quite yet,
but that's a far easier proposition than the iDCT work...
