Im having the same issue. Hell i just replaced my laser and i have that issue still. My halo 3 can play multiplayer and some of the campain. When i get to a certain point in campain it says dirty disc. It does this on the originals and backups. Halo 3 worked fine before the flash and the flash went without a issue.
I don't know about Halo 3, but all my originals and backups work fine, but the only problem is my backup of Soul Caliber 4. Please anyone post if they have the same problem!
