A buddy of mine wants to replace his TiVo, and start recording HDTV programming from his TV. He really likes the small Shuttle cases, so he wants to build a system that would record the programming to the hard drive inside the SFF case. My question is, if I stuff a 3.2GHz P4 (875P) into the SFF case along with a All-In-Wonder 9800 Pro card, will it be enough to record HDTV signal seamlessly without being choppy?
