I recently bought some blank DVD-R's to use in my NEC 3520 with latest official firmware 3.05. I now have 100 Verbatim 8X -R, and 100 Taiyo Yuden 8X -R. Both are from Supermediastore and seem authentic. I've burned test discs for each of these with CD/DVDSpeed at 8X write speed then tested each disc with the same drive and program...and the results aren't that impressive. My results are attached. Any opinions on these or am I just being paranoid???
