I have a 40GB original Apple TV, so not too much room. I always have my iMac up with iTunes running so I can stream my collection of 200 movies to my Apple TV. I sync some photos (but not all) and very little music. 1. Does the Apple TV stream iTunes store HD movies well or do you need to sync those for playback? 2. In stream mode (given #1 works fine), do movies with iTunes extras show up as such, or only when synced? As I get more HD movies from the iTunes store I don't want to have to pick which ones are synced if I can stream those as well as the SD movies.
