I want to get an AppleTV to watch our HD iMovies and show photos to friends on something bigger than a 15" laptop. A couple questions: 1) How much space does a 1 hr HD movie take up? I've ready around 8gb. If that's the case it wouldn't be long before a 160gb would be full. I'm learning towards a 40gb. 2) I've read Handbrake has stuttering issues with the latest ATV update. I have 10 or so standard def DVDs I'd like to have access to. Do they need to be stored on the ATV drive to keep from stuttering or will the stream ok with a new AEBS? 3) You think I'll have any signal issues with having the AEBS, the AEBS will be on the 2nd floor right corner and the HDTV is in the basement lower left? Currently I have an original graphite ABS (802.11b cira '99!) which I want too upgrade. The signal often is dropped across the house.
