I have two questions about Apple TV: 1. It says it streams automatically (or manually). Can I keep my movies/shows/songs downloaded from iTunes on Apple TV and then deleted them off my HD on my MacBook Pro? I'd hate to delete them off my hard drive only to find them gone on Apple TV as well. 2. I read a few threads here about connecting an external hard drive to Apple TV but still don't know if that's doable through the USB port. Can that be done? I already have more than 30GB of songs and shows on my MBP and would very much like to unload it somewhere. Yes, I know I can just put them on an external HD but I'd like to get either a Mac Mini or an Apple TV. $$$ is an issue and a deterent to getting the Mac Mini and so it the lack of HDMI connection and wireless streaming of iTunes. If Apple TV has a 100 or 200 GB hard drive, I'd be buying it in a heartbeat.
