DVD-R Bitsetting, Booktype to DVD-ROM

There has been a lot of debate about being able to set DVD-R media to DVD-ROM using DVDInfoPro. I want to hear from what people think about this?

Rumors are that the newest Nero and HP 520N firmware in the NEC 2500 can bitset the DVD-R to DVD-ROM and also rumored that the Nutech hardware, such as the NU-081 and 082 drives have been able to -R bitset to -ROM.
