Hello All, I am new to the nero cd/dvd speed thing and when I went to do a "disc quality test" it gave me an error message of "Drive does not support this function." I am using an NEC DVDRW ND-3520A and version 4.10 of the Nero Cd/Dvd speed application. Can anyone tell me why Im getting this message?? Thanks. Also- doing this quality test, will it let me know if the media I am using will scratch or skip, is that what this test does??? Again, much thanks.
