the last 3 backups I burned keep on freezing at a certain point early on in the game. the games are super monkey ball step & roll no more heroes 1 ea sports active. i am using memorex dvd+R. i have other games burnt on the same discs from the same pack (nsmbw, prime trilogy) and they work fine. i tried on neogamma 6 and 7, same thing. monkey ball freezes while loading the 3rd stage. nmh1 freezes during the training. ea sports my wife uses so im not sure at what point it freezes. also when it freezes a loud sound plays from the tv. could burning at 8x be the cause of this? or is it the dvd+R that i'm using?
