I was trying to burn a copy of the Zorin OS iso to a DVD+R in Brasero. It started out fine, and then it said "Ejected Medium" and ejected the disc. Then it said that an error ocurred. Why is this happening? I've heard there's a problem with Brasero and Sony discs, but I'm using a Memorex one. I'm kind of a noob to linux, so if you answer, please make it simple.
