Umm, quite certain actually. If you are ever in the US with cable, go turn on The Weather Channel. If you are in a modestly large market (such as a city) then every frame of video you see is being rendered on a Pentium 4-based PC at the NTSC standard 29.97 FPS (or whatever the exact number is). :) > Do you really believe that current Intel Pentium 4 or AMD Athlon XP > can process much higher bitstream HDTV? In my experience the bottleneck is not the CPU, but bus bandwidth. PCI-e has a lot more bandwidth than PCI. PCI-e should be sufficient for HD. -- John Baldwin
