- "Software" MPEG players on the PC platform gain much of their
- speed advantage by using the video card to automatically
- do the YUV->RGB conversion. I think it would be difficult to
- get a reasonable frame rate and decoding quality without this
- kind of hardware assistance, but perhaps not impossible.

- 8 bit does cost you since you have to do a significant amount
- of dithering, but as Michael points out, the bandwidth to the
- card may cost you more than the dithering is costing, depending
- on the card.
