I had the Marvel for about a year. I copied video from my Canon camcorder and edited it, then burned some cd's. It looked great.
I now have the AIW Radeon. Have done the same thing. Works as well as the Marvel if not better. Was easier with this however.
With Both products, the dvd and tv work great. The dvd played much smoother with the AIW.
Overall, I would get the AIW, newer technology, if you can call it that, and MUCH better gaming.
