I made this a general help thread rather than just another random single question on one subject (trying to be helpful!)

I’m trying to use Windows DVD Maker to burn a single MP4 video onto a disc. In order to do this it needs to be in WMV format, I’ve tried using VLC media player to convert it but each attempt has produced a corrupt file. I’d prefer to use a free program as I only need to do this once so can anyone point me in the direction of something that can convert an MP4 into a file Windows DVD Maker will understand (or some other DVD maker for that matter!)?

Many thanks.
