I've tried Verbatim DVD + DL and Sony DVD - R and it just tries to read it you can hear it spinning then it stops then it tries again then it spits it out. I've tried multiple dvds of both brands. It worked once today then I tried to burn to it and it gave me some error, but I figured it was fine this happened before I just need to put it on the slowest speed. But when I reinserted the DVD it just spits it back out. This is what it says about the burner http://puu.sh/4X1OY.png It read a game disc perfectly first try so I don't get the problem.
