YOur problem was the games not working
The Thing Is that when I Insert the xbox 360 game Like Let's Say Assasin's creed Brotherhood or TSU2 the xbox shows : "PLAY DVD"
this is solved as of your LT+ update.
as for the DVD drive issue, i have seen this many times before. And no ma khas LT+ .
Please if you may do this to try to pin point your problem
1. try older games, the ones that gave you problem i.e preap2.5 - are they giving the same error?
2. how old is the xbox (please check the MFR date for me at the back)
i should have mentioned this, totally forgot:
but all in all you need to reburn the games and run them through abgx with auto fix threshold set to level 3
i have
HEARD rumors that updating via XBL will solve this issue, abs i can't confirm it.
.. so find a dvd drive and reburn ... yet try older games
