I purchased 4x dvd+r media and used it with my NEC ND-1100-A. Well it only worked with a few dvd's, plus it skipped bad or no menus, non-working. So I thought my burner was crap, and I needed a faster one anyways. So I bought a Sony DRU-710A. Used the same media and had the same problem. Later I bought 100 Pack Taiyo Yuden 1 47.99(DVD-R47ZZSB8) 8X DVD-R from meritline.com. Needless to say I spent wasteless hours with the Sonic media, TY worked right away. No problem what so ever and I have yet to have another problem. I would not recommend ever buying the Sonic media. As they say, you REALLY do get what you pay for.
