Hello, I am trying to burn mkv files to a blank sony DVD-RW disc. After i convert everything and its time to burn the disc, a pop-up appears saying disc isn't blank, it isn't writeable. I have a CD/DVDRW drive and my driver is a TSSTCorp TS-H492C (Dell Dimension B110). I have downloaded Burn aware home because i thought something was wrong with my burner, but even burn aware doesn't work. I am also using Wondershare and mkv to dvd 3.12. Please Help anyone, Thanks!
