Converting files for a Telefunken TMP420 MPEG4 player

Hi, I have a Telefunken TMP420 mp4 player, it needs its video files to be in AVI(eventhough it’s an MPEG4 player) but it’s very picky about what type of AVI file it’ll play & the file conversion sofware that came with it doesn’t work, I can’t find an AVI codec it will accept, Does anyone have any experience with these particular portable video players? & can you recommend to me some software that can create AVI files it will recognise?

Anyone know?

I’d use Gspot on a file it will play to find out what codec it wants except I don’t have any files it will play, I can’t find my video cables to record directly to it.
