help with downloading movies compatible with the xbox 360
 

I downloaded a movie on limewire and i also downloaded zune so i could connect my pc to my xbox 360 when i did the movie did not show. I went back and searched for the movie again on limewire and saw that the symbol for the MP4 files looked like the zune symbol so i thought it would work with that so i tried downloading it but it says connecting forever then it says needs more sources
