Alright, so I put Gladiator DVD into the Xbox, first three times it tells me that it isn't a CD, DVD, or xbox game. Frustration grows, so I throw it into my Toshiba DVD player to make sure that it is fine, and no problems whatsoever. I put it back into the xbox, and it works. Even more amazing it is able to pass the DTS-ES stream to my receiver, for the first time I can ever recall, the Elite recognized the ES flag! The Toshiba never has done that, ever! T2:UE Dts-es also was recognized. Is anybody else using the xbox for DVD's having trouble with it not recognizing some DVD's? I very much like the improvement in DVD playback from my Toshiba.
