Ok so i ripped the THUG 2 REmix iso onto an 8gb sandisk stick, and for some reason the game freezes whenever i'm grinding around the wire around a boat in the first level after the warehouse, has anyone else seen this?

when i did it with the disc, it froze for a second, then i heard it load something and a cutscene thing happened.

EDIT: I changed the ISO mode to M33 driver and now it works, it was on normal mode.

Oh ok, maybe this will change some problems for me in some games if I mess with the ISO driver.
