Well, I have commented on this several times recently. Voodoo scaling is sh1te so full screen quality at least will be substandard even if the 2D is generally acceptable. NVIDIA is better but not on par with ATI or S3. The hardware acceleration does not neccessarily improve the picture, only off loads work from the CPU. I would assume the full software decode would be the most reliable quality-wise, but again still depends on the quality of the chip's output. The quality of my Savage is superb, with or without motion compensation. I posted a link to an excellent comparison awhile back if you care to search.
