ok found this tidbit on the net

Then we have logical format compatibility issue(s). Probably the very ground for all the controversy around DVD+RW, rather around DVD+RW media not being playable in a whole range of players. DVD+RW Alliance was keen to blame on DVD-ROM vendors, even claiming that they deliberately block playback. But the fact is that format specifications don't explicitly say that unrecognized format [designated by "Book Type" field in "Control Data Zone" of the lead-in] should be treated as DVD-ROM and [in my opinion] it was rather naive of them to claim and expect that the media will be playable in "virtually all players." This deficiency was recognized by practically all DVD+RW vendors [well, apparently by "traditional" DVD+RW vendors and not "latest generation" vendors such as Sony, NEC, TDK...] and a secret vendor-specific command manipulating this "Book Type" field was implemented. So if you fail to mount/play DVD+RW media, you might have an option to
dvd+rw-booktype -dvd-rom -media /dev/scdN
Once again. Not all vendors support this and you can't expect this utility to work with all recorders.
It's naturally not possible to manipulate the "Book Type" field on DVD+R media, that is not after the lead-in is written [which takes place at the moment the first session gets closed]. But it might be possible to control how it [lead-in] is going to be branded by programming the drive in advance:
dvd+rw-booktype -dvd-rom -unit+r /dev/scdN |
So just need to find support for it hopefully in K3b or some other GUI frontend to dvd+rw-tools or growisofs.
