I have a spiffy new 30" Samsung 305t, and I'd like to watch TV on it as well, and maybe play Wii or something. I found some HDTV tuners, but they won't accept HD sources (which defeats the purpose if I use an HDTV cable box). I'd prefer an internal device to external, and firewire to USB. But if it works well, I don't really care. It's for a Mac Pro 2.8ghz 8-core. Ideas?
