Have you tried Orb yet???
I have the 7400 so it doesnt work put I tried it on a PPC and it works great. Also, you can access your files from any other computer so if you can't access them from your mobile device, you can access it via the web via your computer.
It's like a multimedia PC Anywhere but you don't have to download anything to your device. It's web based. You only have to download a program to your PC and leave it running. Pretty cool.
It doesn't let me view the photos tho. I think watching vids and listening to mp3s is a good trade off. 🙂
