Ever since I installed my viper which works fine according to expected functionality, I have been having some issues with my burned discs. The only games that I have even been playing on there are games that I have backed up myself. I haven't tried playing too many other backups. I'll be playing and all off a sudden the black screen comes up that says that the disc can not be read. Does anybody know why that might be? I was going to perform the laser tweak on the system but the ohms were within range so I didn't need to do it. I have been using the viper backup dol that you burn to a disc and load from the cobra bios (don't remember the name) I have been burning at 4x speed? Is that maybe why?
