After the Mad Dog 2.F9 firmware and Liggy’s modified 2.18 firmware came out with support for BookType setting of DVD+RW media, there has been some discussions on this formum whether this will work with DVD+RW media that has already been used.
I haven’t really seen any success stories in relation to this, but I just found two ways of doing it that seems to work with Liggy’s modified 2.18 firmware; I didn’t try it with 2.F9 so I don’t know if it will work there.
One way of doing it:
Nero CD-DVD Speed 3.50 (www.cdspeed2000.com): By selecting Erase Disc… from the Extra menu, and then using the Format button, the disc is erased and formatted with a BookType set to DVD-ROM - provided that this BookType setting is already enabled in the firmware of course! A Quick Format seems to be sufficient.
Another way of doing it:
DVDInfoPro 2.63 (www.dvdinfopro.com): By selecting the Erase/Format button and then pressing Go, the disc is erased and formatted with a BookType set to DVD-ROM - provided that this BookType setting is already enabled in the firmware of course! A Fast Format seems to be sufficient.

Disc after format and bitsetting:
