Book type DVD+R setting

[mjhmeyer]

I am on Suse 10.0 and replaced my old Yamaha CD writer with the Pioneer DVR 112D dvd writer (is a slave to the cdrom drive).
I made no changes in Suse Linux.
The device is at /dev/hdb and Yast/Hardware/CDROM drives shows this:

CD-ROM Drive/F5E /dev/hda
YAMAHA CRW2100E /dev/hdb
PIONEER DVD-RW DVR-112D /dev/hdb
CD-ROM Drive/F5E /dev/hda
PIONEER DVD-RW DVR-112D /dev/hdb

Ie. the old drive still shows up and the new one is shown twice.

K3b recognizes the pioneer drive correctly and I was able to read the Suse DVD as well as burn (k3b) and later read a DVD-R disc.

I have never been able to burn a readable DVD+R with k3b on FujiFilm 8x blanks with Tayo Yuden dye. The burn is always successful but the disc cannot be read:
k3b believes it is an Audio disc and complains that CDDB entries are not found.

I am using dvd+rw-tools version 5.21.4.10-9.
I have downloaded the tar ball of the latest dvd+rw-tools but not installed yet.
In the documentation I have read that the problem probably is that the DVD+R booktype bit may not be set correctly (to dvd-rom) and that I should try to set it with the command

dvd+rw-booktype -dvd-rom -unit+r /dev/hdb

before burning the disc. When I do this i get the following error:

linux:/home/cpp # dvd+rw-booktype -dvd-rom -unit+r /dev/hdb
:-[ BTC_FAh[3] failed with SK=5h/ASC=24h/ACQ=00h]: Input/output error

Another problem I have is that the burner does not burn at 8x speed if I set the speed in k3b at 8x, rather it may burn at 12x or 2-3x.
When I try to read the DVD after burning I get the error message

cdrom: This disc doesn't have any tracks I recognize!

from dmesg.

I am pretty desperate.
All help is much appreciated.

It looks like the drive needs a firmware upgrade.
Pioneer only provides a Windows executable to do that.

How do you do that if you don't have Windows?
