Okay.. I was doing everything fine.. copying etc.. and one day... (the other day) the disk will not finalize now. It reads the disk, and when it writes.. it gets to the end and it says (Writing Disc Error) I took out the dvd burner and put it in another machine and it works.. So could someone please give me an idea why this is doing this? Its obviously not the burner... so i dont know what to do.. please help.
