Following weeks of headlines touting strong sales for Blu-ray discs, rival next-gen format HD DVD looked like it had its own success story in the making with this week's HD DVD release of the cult hit 'Children of Men.' The disc recieved a stellar review at High-Def Digest, and went on to out-sell the most popular Blu-ray discs on Amazon. But now comes word of apparent incompatibility issues with the Xbox 360 HD DVD player, with some (but not all) consumers reporting that even multiple returns of the disc are unplayable on the format's leading playback device.
