Just got it set up and so far so good. My configuration: -Imac in upstairs office. Latest version of itunes, external drive with 45,000 songs and about 25-30 movies in the itunes format. -Airport Extreme Router (latest version) -Apple TV downstairs connected via HDMA to 42" widescreen Plasma tv. -Right next to the ATV is an Airport Express Base Station. So I got everything set up and connected the ATV to my network. My utlimate goal is to stream as much as I can and I had no problem viewing/playing things in my itunes library. The movies look great, the music sounded great. Some questions: 1) Will I pick up any speed by plugging an ethernet cable from the ethernet port on the ATV to the ethernet port on the Airport Express Base Station? 2) Even when not streaming content from my computer, the ATV seemed very slow. I would click to do something and it would take sometimes a few seconds, to up to a minute to act/register. Is that just because it was slow because it was trying to sync. 3)I only got a 40 gig so I'd like to avoid syncing wherever possible and be able to stream as much as I can. Any hints or tips regarding that would be appreciated. 4) If I'm in Itunes on my upstairs computer and I do sync some movies to the ATV from upstairs but then want to delete them, can I do that from upstairs on itunes or do I have to do it on the ATV menu itself? Anything else anyone can recommend for this set up would be helpful.
