XBOX is sensitive to HD brand.

OH MAN
Well I went to the drive that worked and wiped out the X drive.
Guess what it stopped working.
Well that made no sense right?
Well, that allowed me to connect the dots.
The first time a game is run, you have to let it run through all of the opening video and stuff (not all games, but GH2 and Fable at least).
Once it's done that.
No problem.
Eventually the start menu did appear for me - but I ws impatient and did not wait long enough at first. Once I let it get to that point. Everytime after that I can click start and skip the opening video no problem.
Can you spell smart?
