you must update to Nero Burning ROM 18.104.22.168 first to have the same screenshot...
That's the whole point, I HAVE 22.214.171.124!
Anyhow, when I insert a DVD+R, the booktype section in Nero suddenly appears…
I have chanced de default booktype for +R and +R9 to -ROM with the WinBType utility, and then (for the first time) I burned a DVD+R with CloneDVD.
I was pleased to find out that, indeed, the booktype was automatically set to DVD-ROM, and that my stand-alone DVD player reads the DVD!
Back to the +RW issue:
So far, there is no utility where I can set the default burner
booktype for +RW to -ROM, and the media
booktype for +RW remains +RW, whatever burning tool I use, and however I erase the +RW.
