I'm thinking about getting an AppleTV primarily to watch our edited HDVs (also need to get a HD camcorder). Which is a better set up: larger 160gb model, a hard-wired external USB2 HD (which you could get a 250gb for about the same difference), or an external HD on an Airport network? I have a 500gb FW800 but its used for my main computer. I'd LIKE to be able to move the AppleTV between 2 TVs but not a requirement. Thanks.
