i put some albums onto the archos. they all appear to have gone on to it properly but some just are not on the device. When i plug into the computer and go into it via the computer they are all there but when i just go through the archos they are not . When i checked closer i noticed the one that said windows media in the type section played and the one that said mp4 didnt. How can i change the mp4 ones to windows media. Or is there another solution
