I have a Sony mp3 player (E series if that matters), and a video I made using Windows Movie Maker. It is a .wmv file, which is compatible with the mp3 player, so it says, but it won't work on it. I tried clicking on "Media", then "Convert/Save..." to change the audio and video codec, and it never changes anything or seems to do anything at all. Could someone tell me if there's a protocol for this?

I'm obviously not understanding something!
