It's a brand new samsung DVD RW drive(i know, i know, don't give me that stuff about samsung drives....they have the best ever error correction) and am not able to burn stuff on a <sigh> brand new moserbaer dvd+rw which says 4x. But both Nero and Roxio easy cd creator report a writin speed of only 2.4x and nero aborts with a "illegal disc" error msg but roxio acts like its writin and at the end, there's only a blank disc.....
