when I try to play burnout 3 all cars are stuck at 30 mph, which makes the game unplayable. when launching from retail disc, it works fine, but I prefer not to have the DVD drive connected.

I have tried pal, riped my own, and NTSC. all with the same issue.

console is a 1.6, with Aladdin XT.

anyone had this happend to them before?
