This has been discussed before. CPUs aren't fast enough (see the archives
for examples). Therefore we MUST have some sort of hardware assist.
I don't remember that. I think people figured out that on not too old
hardware, they could do the full decoding in software with no
problems. On the other hand, we will be providing YUV to RGB
conversion, which will lighten the burden a bit.

OGD1 is one thing, but OGC needs mpeg decoding or why bother?
We already have hw that can't do video, don't need another.
One of the main reasons to make OGD1 is so that we can full test the
GPU design before it goes into an ASIC. We can't afford to have an
expensive mistake. So, if we can avoid it, no logic will go into
TRV10 that wasn't fully tested and integrated into the OGD1
implementation of OGA.
