I had the same prob

Sry to tell u this all but NERO doesn't affect VGA at all. I have Nero and VGS DOES woek well.

Anyway I had the same problem, i found out that it was because I had desactivated the auto launcher. Maybe it's the same thing with u, because when it was disabled it was always saying "waiting 4 a CD" or "loading" but the game was never starting.
