hey,
what i mean is , while I'm in the game, playing the mission, right side bar would pop out and says "disc is dirty please clean it and try again". even after i clean it with proper cleaner, it still gives me the error at the same area or near it. but like I said I burned like 4 of these and when these happenes i put in different backup of GTA4 and try it. normaly it will by pass the area i was having problem with.
but one time all 4 of them was giving me error at the same area so i tried to burn one last time but this time with cloncd. and I was able to play it with out error for several hours. still fine.
but don't get me wrong. Imageburn is a great program and I have lot of discs that was used by imageburn and still works great. only certain title is having a bit of problem with me.
i think it's just my pc that wasdnt getting along too well with imageburn for some reason. best way to find out is try both program and see what works for you.
