I have the new AppleTV. Preordered it and all. I don't think I have once played a movie without the thing skipping and having serious loading issues from my iTunes Library. If I play a 720p video I have that I've purchased from iTunes it skips and has to buffer every 5 minutes. So I let it sit paused for the buffer to be a reasonable size. Never fails, it'll just skip again in 10-15 minutes. However, I rented an HD movie from iTunes directly from the box and that played without skipping once. So I'm thinking it's something to do with my mac pro or something is screwy with Home Sharing. I've turned Home Sharing off and back on, on both devices. That didn't solve it. I've even tried switching all the crap on my Airport Express to try to improve things. I get 5/5 bars in the network setup area. I just don't get what is causing this thing to have issues like this.
