 When I fire up k3b and go to:
settings->Configure k3b->Devices

It says that the drive will not write DVD+R(RW)S
That is not correct, it does and works under XP.
I upgraded the BIOS to 1.10 with the same result.

What does "cdrecord -prcap" say?

That reports what the drive says it's capable of doing.

I have the same problem.
The result is sudo cdrecord dev=/dev/cdrom1 -prcap

Device seems to be: Generic mmc2 DVD-R/DVD-RW.

Drive capabilities, per MMC-3 page 2A:

  Does read CD-R media
  Does write CD-R media
  Does read CD-RW media
  Does write CD-RW media
  Does read DVD-ROM media
  Does read DVD-R media
  Does write DVD-R media
  Does not read DVD-RAM media
  Does not write DVD-RAM media
  Does support test writing

So it seems that device is not weel recognized.

I think it may be that cdrecord doesn't report DVD+R(W) capabilities at all. Having just tried "cdrecord -prcap" on my own drive (which I believe to be capable of writing DVD+R(W)), there again is no mention of DVD+R(W). I've never actually tried writing that type of media.

Does growisofs work? It's part of the dvd+rw-tools package and it is supposed to understand DVD+R(W) media properly (see also http://fy.chalmers.se/~appro/linux/DVD+RW/ for lots of technical discussion).
