Windows Media Player should have no problem playing MPEG files (as far as I know). See if VLC player will play the file (link in my previous post). If VLC won't play it, it's probably a fake file. Do you know how to check files with Bitzi before you download them? I highly recommend it...if there are many sources but no Bitzi rating, it's probably fake. If a file has only one source or several sources but no Bitzi rating, there's a chance it's a valid file that no one has bothered to rate yet.
