Hi guys!

I do not know was it my lack of knowledge about linux (I'm newbie), or this jaunty or the burner software or my burner(Slimtype DVD A DS8A2S)..

I'm using acer aspire 4935 with ubuntu 9.04 jaunty..
I already tried with brasero,cd creator, k3b....problem is the same...
burning process complete successfully but when verification process it came out to be error at 80900....in k3b...

I already search how to burn the iso...they said I have to burn to slower speed at 4x-6x....but all those softwares just could give at 10x for the lowest burning speed...

so I tried and the same problem occurs...i,m not sure whether at the same location or else between those 3 burner softwares...but the same problem...
already tried to use the boot cd but during post installation came out an error...

so I want to try burning slower than 8x but I do not know how to do it, because those softwares just gave me 10x as the lowest speed they could achieve...

the other days I have to use windows platform to burn the cd's at lowest speed at 4x....and the cd's worked fine...it's embarassing becoz I want to show my friends the great things about linux...but a simple task linux cannot do....

Any suggestion?
I'm trying to install linux on to my friends laptop...he's fed up with windows...

I don't understand. Most DVDs aren't even ready for speeds greater than 4. But you can open the settings menu in K3b and switch off the speed auto-detect by setting the speed by hand...

I'm using the latest version of k3b
I only could find Settings>Configure K3b...
I could not find any words of "speed auto detect"...in the configure menu...
Any suggestion??

Okay, I had a look again. Click on "extra" / "copy DVD" and you get a popup which among other things lets you choose the speed.

Hi there!

I will try it, but now I use the imgburn software using wine...
It worked... I could choose the writing speed to the lowest for the DVD and burn and verify successfully...if k3b has a bug in jaunty, hope someone would fix it....
