I tried re-entering my address and it still doesn't work from AppleTV. I just get the same Apple I.D is not recognized or your password is incorrect error. NOTHING I do (unauthorize/reauthorize; unsync/resync computer, etc.) makes a bit of difference. Both of my AppleTV units REFUSE to play purchased content or even connect to YouTube. It just plain SUCKS. AppleTV is FAR from "It just works" because it doesn't work at all with iTunes here.
I wonder if it'd make any difference if I used my PC to sync instead or using Leopard instead of Tiger (Leopard is slow on my 1.8GHz 7448 G4 with a Rage 128 card so I haven't been using it, but my Radeon 9700 Pro should be back tomorrow; I got a 'missed you' delivery notice from the Post Office today for an express package, so that was obviously it; maybe Leopard will run better then. I haven't been able to try the 9700 Pro with Leopard since I got the 1.8GHz upgrade, but it was slow with the 9700Pro with the dual 533 G4s that was in it before, so it still seems strange. I only get an 11 for User Interface in Leopard right now; I get almost a 100 in Tiger with the same computer (1.8GHz 7448 G4 Digital Audio + 1.5GB of ram + Sonnet Sata only for hard drives which are 2 500GB models and I get 75Mb/sec on them so it makes NO sense for Leopard to suck so hard with this computer other than the graphics card, but even then... it's a 100 on Tiger with the same card! There should not be a 10-1 difference like that, IMO regardless of the video card).
