I purchased a pack of DVD-R by mistake as I thought those were regular music CDs. So, of course, it didn't work with my CD recorder has it does not support that. I always used regular music CDs so far to do my backup. However, the DVD-R can hold up to 4.7 Gb. So, is there a way for me to use those instead so I could store much more content on one CD? If yes, what CD recording software should I obtain to do that?
