I just noticed that DVD +RWs are being reported by CDSpeed as DVD-ROM when I burn them with the 4163B. I was aware that bitsetting was implemented in Nero for +R but these seem to be auto bitsetting in non-Nero burns. Is there something we missed in A103 or is it possible CDSpeed is goofy?
I’ve used all of the recent CD Speed versions that were released to the public. Booktype display always worked correctly. DVD+RW booktyped to DVD-ROM? I haven’t tried DVD+RW disks since A101.
That might be a problem I have seen earlier that couldn’t add data to a +RW because my computer recognize them as DVD-ROM.
Of course if it’s not the case then it is superb.
On my new, just formatted DVD+RW no bitsetting occurred using nero
and setting booktype to DVD-ROM in the recorder options

I think I might have an answer. The +RWs I was using were previously recorder on the 3500 with auto bitsetting. It would seem as though erasing and rewriting leaves the bitset intact. Nice find. 
What bitsetting has a 3520?
Does anyone knows?
Thank you but it doesn’t say exactly.
I want to know if has +RW bitsetting or what other type.
On the graph for 3520, all the latest firmware versions seem to support DVD+RW bitsetting.
:o
Ken which drive could you propose for changing my 8163B.
DVD-Writer of course with fast DVD ripping but cheap.
Thanks.
