Up until a week or so ago I could burn any disc no hassles, but all of a sudden all my Xbox 360 discs now are burnt with no errors but show up as Play DVD on the 360 and if they play it says to play this disc put it in an Xbox 360. Can anyone help me as I have tried everything and I am almost up to a whole spindle of dual layers wasted. I have tried it with Verbatims and Riteks and it made no difference. I have also tried it on a different PC that worked last time and for some reason it did not work this time also. Has there been any extra put into the Xbox 360 games to stop them working??
