Cyberdrive drives use the Phillips Nexperia chipset, which means that they will burn DVD+R media better than DVD-R (although that quality gap is shrinking all the time).
This of course opens the bitsetting can of worms (not all players can play DVD+R discs unless you use bitsetting) but Cyberdrives usually default to bitsetting to DVD-ROM (so in short you can ignore what I just said until you're further along the learning curve and it makes sense ).
Try some DVD+R media.
Generally, "made in Japan" media is better than Taiwanese media. Try to find media of any company that is made in Japan. (Note that almost no companies that apparently make DVD media actually make it - there are only a few manufacturers of CDs and DVDs in the world and they sell their production to these companies who retail them.)
