Mpeg2, arguably, requires the least amount of cpu to display because there is very little to decompress like mpeg4. So, while mpeg4 takes up less space, it takes more oooph to play it. The HD TV stream (I think mpeg-ts?) is just plain old lots of information. The nVidia cards are nice because they support hardware acceleration on the output end, while the pvr-x50 does the acceleration on the input end. Paul
