Switch types of disks, switch brands, switch burn speeds, even switch to +R which are supposed to be more compatable.
It also appears you are new to posting on forums because you posted your email and you screwed up your thread title. The link in my signature can help to prevent you from screwing up anymore.
Incase you decide you don't care to read it, let me explain something. Nobody here is ever going to email you if they "solved" your problem. The whole point of forums is to have problems solved publically. If you can't bother to come check up on YOUR problem what makes you think we can be bothered to email you. It shows your lazyness and lack of respect of the forums. If you really are going to use us like a wh*re, there is a box you can check when you are writing your post (have to click go advanced for this to appear in a reply) where the forum software will shoot you an email anytime someone replies.
