Okay I have had the AppleTV since it came out with no problem. I have always streamed from a MacMini with the iTunes library stored on a FireWire Drive over Airport extreme (A/B/G). I just recently got the new Airport. I set it up with the iTunes library on two external USB drives with a USB port as an Airdisk, worked great until yesterday. I started to stream a movie (Bable 3.7 GB 720p) that I had watched before with no problem. It starts to stream and then buffers about every 5 seconds. Tried it with about every movie (I have over 500 gigs of movies) nothing worked. I tried using streaming from my N enabled MacBook Pro with 4gigs ram same problem. My set up is Airport Extreme(N) network with an Airport Extreme(A/B/G) bridged. (I want a pure N network and have the A/B/G for my iPhones and two older Macs). All the airports and the AppleTV are up to date with firmware etc. OSX 10.4.10 on all Macs. Here are the different things I have tried: MacBook Pro connected to Airdisk (Airport set at N only 5ghz) MacBook Pro connected to Airdisk (Airport set at N only 2.4ghz) MacMini connected to Airdisk via Airports ethernet with Airport on the computer turned off (so it did not pic up the G router). MacMini connected to Airdisk via Airports ethernet but streamed to AppleTV via the airport(A/B/G). All of the above with the AppleTV connected to the old Airport network bridged at G and with the AppleTV networked with the Airport N router. Any ideas what Im doing wrong?
