No. The DVP642 can play avi with mpeg4 video. I have a DVP 642 and I play avi's all the time.

I suspect more a problem with the ffourcc. Try to change it to DX50.

I didn't know the DVP642 could recognize the mp4 container. I will do 
some test myself with it. I'm also confused about the fact that you can play
the video in the mp4 container. May be the ffourcc is not the solution after all.

If you like to experiment, try to make an avi with encode2mpeg using the option -profile.
The resulting avi should play on the DVP 642 (if not, let me know).
