no, AVI files
Sorry, I got confused by the "AVI for M3".
All dpg converters are for Windows, you would have to run them in an emulator. You could use
Tuna-viDS, it's an AVI player that plays Xvid-encoded avi videos on the DS. You have to resize them, though.
QUOTETuna-viDS plays videos with the following format:
* Video: 256px wide, up to 192px tall, up to 12fps, Xvid encoded, non-interlaced
* Audio: Stereo or mono MP3
* Container: AVI with chunk index, video must be the first stream (fourcc 00dc)
