I have got a new Laptop and have installed Media Center 2005 on it. Also I have set up the Xbox 360 to connect to it. I can use the Xbox as an extender just fine. It loads up and i can play music, watch tv through my laptops freeview and look at pictures But I cant play any video files at all. I have a large collection of Mpeg2 files, HD content and WMV files, and none of them play through the Xbox. They play on the laptop, both through media player 10 and windows media center. So my codecs must be in order. I use Nvidia purevideo as my mpeg codec and that works fine. When I go to my video on the xbox media center it seems to stop for ages (as if it is trying to load something, or search) before i can move the selection box to a folder to view the video files. Once i am able to move and select a video the circle that appears when media center is loading a file just spins. What is going on?
