Hey guys

I am having a lot of trouble playing .rmvb files in windows 7 media center, i can play avi, mkv, mp4 and other files fine. But when i try load a video that is rmvb i get this error:

CANNOT PLAY VIDEO

Media Center cannot find the specified file. Be sure the path is typed correctly. If it is, the file does not exist at the specified location, or the computer where the file is stored is offline.

Can someone please help???
