I just upgraded an older pioneer dvr a05 to a new Pioneer Dvr 112d. The older drive worked fine but I wanted a faster drive that does DL discs. My issue is that my single layer discs fail almost everytime when using clone dvd and my DL discs, although they work, when I look at the burned image on the disc it appears that only half the disc is used. Any suggestions? Btw I did upgrade firmware on the burner after I had the issue.
