Hacking Rock Band 2 Problem

[maarten66]

I have downloaded the Rock Band 2 iso from usenet, it's a non scrubbed version. I burned it with imgburn at 4x on a Pleomax DVD-R 16x. When i launch the wiigator backuplauncher V0.3 gamma with 002 fix it doesn't see the title of the disc or anything. When i try it with the Softchip loader, it give the name of the game, but then gives a loctl error in the loader screen. What goes wrong?
I have a pal wii with V3.3E.
