wildennis, try using dvd2xbox. I rescently found xbcopy ot woking for me too well, as in I get wierd errors when copying. Also, it autopatches games so you wouldn't have to upgrade bios.
Also wanted to ask, do you have a Thompson dvd-rom

? Is the hole in the drive tray a U, a circle, or one with 2 small circles in the corner?
2 O's = awsome
1 circle = cool
U shape = OH MY GOD, KILL ME (a little exaggerated, but u get the picture)
