I know nothing about Xbox Media Center so I had to google it. lol (I suspect it's a setup issue.)

This is what I found out: ... be used to play and view most video/audio/picture formats such as MPEG/MPG, VOB, AVI, OGM, DivX, XVID, MP3, OGG, JPG, GIF and many more direct from a CD/DVD in the DVD-ROM or of the Xbox build-in hard disk drive, it can also play files over a network (LAN) from a PC via an "XStream Server" application or from a Windows (SMB) share. It has playlist + slideshow functions as well as the ability to function as a full replacement Xbox dashboard. These and more features enables the Xbox running XboxMediaCenter to fully function as a multi-media jukebox. XboxMediaCenter also known as "Xbox Media Center" or simply "XBMC".

Things that are not supported in XBMC yet:
- DVD-movie playback, - Audio Visualization, - Matroska file container, - Windows DLL's (WMV/WMA 9), - FTP-Server, - SHOUTcast, - TV-Guide

Note! Normal retail Xboxes require a modchip with hacked a BIOS for XboxMediaCenter to run.
