I really need these questions answered.. 1. Could I get a TV tuner to connect to a PS3 and a 24" iMac and not loose high def? 2. When high def comes out is there a digital tv tuner option that lets me get high def? Ok thats all the questions I can think of.. I ust really nee to know it because if both of them or just one of them is a no I might go for a 17" iMac and buy a hd ready tv..
