This is a REALLY serious problem in Ubuntu. I have switched from WinXP and this is the only thing that really makes me angry about Ubuntu :/
Anyway, there are lots of people having similar problems - http://ubuntuforums.org/showthread.php?t=128721 . Plus, this bug ticket should be merged with bug #31709, as it's exactly the same thing. K3B has nothing to do with it, 'cause people are having this problem no matter which app (or what kind of writer) are they using - I personally have it in K3b, Brasero and Nero.
But first things first -- I've got LiteOn SOHW-1633S ( http://www.liteonit.eu/index.php?option=com_content&task=view&id=36&Itemid=67&limit=1&limitstart=1 ) with BS0Y firmware. It allows me 16x burns on DVD+R blanks. And it does - in Windows. In every app - Nero, A120 - you name it. Burning full 4,7GB DVD takes no more than 10 mins in Windows. In Ubuntu, on the other hand, I have never managed to achieve speed above 4x. Usually, burning full DVD takes me 40 minutes or more.

Here's my hdparm /dev/dvd (if it helps)
/dev/dvd:
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
HDIO_GETGEO failed: Invalid argument
And hdparm -i
/dev/dvd:
Model=LITE-ON DVDRW SOHW-1633S, FwRev=BS0Y, SerialNo= 227,w/IORDY: 120}, tDMA={min: 120,rec: 120}
Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=0kB, MaxMultSect=0
(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
IORDY=yes, tPIO={min:

DMA modes: mdma0 *mdma1 mdma2
UDMA modes: udma0 udma1 udma2

Drive conforms to: Unspecified: ATA/ATAPI-5
* signifies the current active mode
Right now I'm using this hdparm syntax to set my writer:
hdparm -d1 -c1 -a8 -u1 -Xmdma1 /dev/hda
Anyway, I'm not sure if it's DVD+RW-TOOLS package problem, as I don't think Nero is using the package (and it's very slow too).
Someone -- PLEASE, make this bug really important on the list. It's really an annoying issue.
