It's not done by the CPU, it's in the GPU, so to some extent, that does
represent 'hardware', but much of the work is done by Gen4 instructions
running in the GPU, so I think of it as 'software'. Building a graphics
system that couldn't do H.264 wouldn't make much sense...

Sure, we all do.

Yes, these are the same

Yeah, I've found the capabilities in the SDVO chips to far exceed what
you can buy in a packaged board. I don't know what can be done about
this. I haven't even found a dual-link DVI card.

The DVI cards will do 1920x1080p quite nicely, with reduced blanking,
that should be within the DVI spec.

Yeah, the external card builders are lagging what the chip can do. I
hope this gets fixed soon.
