OK, I burned about 10 DVD's with this drive. Previously i have LG GSA-4082B, which was excellent, but nowdays it not support new media.... so i bought BENQ DW1620, seeing here excellent review, and user comments, and update firmware to B7V9.
Here are some interesting and dissapointing result I have with Ritek R03 media:
Notice that is not recognized by my DVD-ROM drive, and Benq says it have capacity 8191.63 GB????????? And Benq do not recognize media code, as You can see neither with DVDInfoPro, or Nero CD Speed.
Other thing that dissapointed me is DVD+RW problems. I burned one Verbatim DVD+RW @4x, and one Memorex DVD+RW @4x, but they are not recognized by Benq nor Asus DVD-ROM. It says: no inserted disc.... I have read that Benq have some problems with DVD+RW, but this is VERY BIG problem.
So, is it better to use older firmware for DVD+RW?
And did anyone have idea what happened to Ritek R03, after this burn.... or I have to change my drive, because I am dissapoint now.
