when i download from LIMEWIRE i choose the videos in .mpg format when i finish downloading i believe my computer use to automatically choose .wmv if im not mistaken. i dont have any on the computer at this time to double check. when LIMEWIRE finishes the download it saves it as a .FILE i can still play the video after i choose a player from a list. but i cant do anything else with it such as put it on my .MP3 player or the such cuz of the file format it puts it in. thanks.
