Let me just say, I'm not so sure what took me so long...but I finally softmodded an old XBOX I had laying around. Its Thomson drive had seen better days, and I simply replaced it last Halo (Holiday) season...anyway, I figured it would make a nifty Replay client for my bedroom after reading all the positive stuff here. Well, let me jump on the bandwagon. XBOX Media Center is an extraordinary program and does a remarkable job at playing EVERY format (including Replay MPG-2) of media I've been able to throw at it. It streams everything flawlessly. Simply one of the slickest multi-media devices I've ever used.
