I know. if I want to watch TV, why do I need a computer? Well, I do both, and my TV is dying. Rather than replace it, maybe there is a way to hook my cable TV up to my iMac? I'm sure somebody's asked this before, but I can't seem to find anything.
be careful when you buy. get the 2008 version if you want clear qam (HD) channels. basically hd channels through cable without the digital box. macsales has it for 129.99. the 67.99 one is the same, but without clear qam
