Ok, first-did you install the software from your computer using Acivesync? It sounds like the programs might not be working because it wasn't installed properly.
Second, are you sure you have the correct video type for the software you are using, ie: AVI for PocketMVP?
Those are the only things I can think of. Video plays beautifully on my Axim 300. I used the quick guide to reencoding video found here

If you can't get video to work using that guide, I don't know what the problem is. The guide works great for most people. Good luck.
