I just picked up one of the MyHD 120 PCI cards so I can capture and archive HDTV. (not going to hold my breath waiting on Dish to activate the Firewire output on my 921!). My question is this, if you have one of these cards or are doing any kind of video capture on a desktop PC what do I need in a computer? Obviously large amounts of hard drive space but what type of video card is necessary? Is the built in Video card good enough or should I spring for a Radeion 9000 pro (128MB) card? How about sound cards? Tell me what computer your using to do your video capture. Any problems to look out for?
