I am haveing trouble knowing which EyeTV to buy. I want to be able to watch Digital TV on my mac, aswell as being able to plug in my xbox 360 and play it using my iMac screen. Also I take it all EyeTV's come with the software and episode guide. But do you have to pay a yearly charge to get the episode guide, or anything rediculous like that? I would really appreciate it if someone could tell me which one to get. Thanks!
