if it's the t2 that came out with the HD content on it, that's a tricky burn to run, but it still should be possiable. Try buring it at a lower speed.
As for the special edition, it ONLY works with Media Player 9 and above, because it downloads a license to play (Digital Right Management crap) and then allows your computer to play it. Now you can backup you licenses, but it also re-downloads them every now and then.. so if you want to watch the special edition HD, you will have to use your computer.
InterAct is the program they want you to use on your computer to play the Movie. (it comes on the disc.)
