Im looking for a bus-powered tv tuner, just to watch tv with, i dont care about recording shows etc. I'm on a powerbook. are there any other bus powered tuners for the mac? besides for the mytv2go i heard that its terrible. also are there any hdtv and analog tuners in one (the eyetv500 is only hdtv /digital, and cant pick up regular analog). there are so many tuners in the PC world, how are there none for mac?
