I'm new to this, and this is not my main HT system, but I'm trying to figure out how to get a tv card that will work with my SGI flat panel. Initial attempts with ATI TV Wonder have failed. I don't have a satellite, so no HDTV yet, just trying to get a picture. P4 computer with 1300MH 389MB RAM, 100+GB HD, WIN2000, SoundBlaster Live! 5.1 sound card.
