What burner do you have I've got to get one.
I'm not talking about the speed you set through the software you're using, but the actual speed that your burner is burning at, which are two different things the 48X is what your burner is capable of. I set mine at 32X and haven't it reached yet. I've got a 48X Tobshiba reader and I haven't found a CD-ROM yet that can be read at that speed.
There is a differance between capable and actual speeds Nero has utilities that can tell you that. As for a crack never heard of one, firmware controls the way and speed that you burn.
