just use Media Player Classic
i dont know which format it doesnt play, coz it plays all the media files that i know of, including mpeg media files, windows media, real media, quicktime, DVD audio/video, avi, flash, 3gp, mp3, midi, wav, ogg, etc....u can even use it to play to streaming audio/video and it even supports image files. its a standalone executable, no need for an installation, just dload the zip file, unzip mplayerc.exe (4.62 mb) to any folder and viola! and the best part id that its not a resource hogger like other s/w's.
