5.1 to 2 Channel - Any compet. for Magnum MD-10

I'd like to keep my 2 channel setup but hate listening to the 2 channel mix on DVDs, it is of much lower quality than the 5.1 mix. Magnum Dynalab makes the MD-10 which takes AC3 5.1 and converts it into a 2 channel "virtual surround". I believe this would be much superior to the 2 channel crap they put on the DVDs.

At any rate, they say it is the FIRST unit of its kind. So my question is what else does this, and does anyone have any experience with devices like this. Thanks for the help.
