For example when using Nero CD-DVD Speed application I can read under "Disc Info" which DVD recorder device was used during write.
Is it possible to omit/remove this information when disc is burned?
No. It is built into the firmware for just about every drive I've seen. It's part of the DVD-R specification, I believe, and there's never been a tweak for any firmware to turn that off.
Somehow I thought so.It's absent from DVD+R though, right?
