problems with k3b .. and dvd writer

pieter_parker

i have a benq 1640, a seagate 80gig ide hd, and good verbatim 16speed dvd discs
some time ago .. i used windows with this hardware and this discs, i burn with nero often data dvds, i was able to burn with 16speed
now in k3b, a dvd takes 8 minutes .. or a little bit more, i use the same hardware, the same discs, but why is it slower??? in k3b i have never see him go over 10speed

have you tried burning as root?

is the speed set up correctly in k3b?

are you doing alot of disk activity?

Hello, I have the same problem:

The burn speed of the device (benq dw1640) was fine (real 16x) at windows2k (nero), debian sarge (k3b), and slax livecd (k3b). But using Gentoo, it takes a bit more of time, with k3b as well as gnomebaker. Interesting is, that with nero for linux the speed is higher than with k3b. I tried several kernel options, switching from gentoo-sources to vanilla-sources, and remerging k3b with other use-flag (hal).

I already postet the problem in another (german) forum (http://www.gentooforum.de/artikel/10250/k3b---Brenngeschwindigkeit-zu-gering-cddvd.html), and I asked some guys in IRC, but the problem is still unsolved.

Anyone using gentoo who can write DVDs in 16x speed with a burning software not nero?

I am thankful for any information/ideas!

I hope you have solved the problem in the meantime and can tell me how?

Greetings,
Christian

I would burn a dvd with cdrecord 2.01.01a23 and one with growisofs 7 in verbose mode and compare the burning time. Burn as root as long as you are trying to solve the speed problem. k3b is just a frontend for dvd burning with growisofs (dvd+rw-tools).

k3b is just a frontend. You do the burning stuff with dvd+rw-tools. How is the speed with cdrecord?

Thank you for your replies!

I tried manual burning with growisofs7 and had the same problem. With cdrecord I got the same results, but interesting information:
