I borrowed Halo2 from a friend, I could not load campaign what so ever, xbox would freeze, jitter, and all that stuff, system link works fine (use xbconnect and xlink). I copied it to the hdd too, still didnt help.

my xbox is v. 1.0

has anyone else had this problem, can someone help?

Anyone? the reason I posted this in hardware is because I don't think its the disk, works in other xbox's.

And I replaced the laser in my dvd drive like, 2 months ago to fix DREs. The xbox is softmodded with EvoX and a flashed BIOS. I cannot for the life of me figure out why its not working with just Halo2. Everything else functions 100%

Which method didn't work from HD or DVD? Try to delete content of CACHE directory and content of the X, Y, Z partition. Also goto msdash and delete HALO 2 game saved.

Ps.. Don't delete the CACHE directory but the content only.
