Ok, I have XP Media Center Edition and I get it hooked up to my xbox 360 no problems. However there are two things that bother me. #1 xbox media center extender wont allow xvid.avi files to play. This really sucks cause i have alot of divx movies I want to watch. The solution is to convert those files into wmv which isn't that bad except it takes alot of time to convert those movies. #2 I seem to have to re-establish my connection from my xbox360 to my media center every so often. It thinks its a new xbox360 detected and not the one i already setup. I'm still not sure whats causing this. If anyone else experienced this or has a solution please share.
