When I try to burn a DVD with K3b, it says that the highest speed is 1x. But I know its 4x. Does anybody know how to fix this?

Will my kernel (2.4.20 -- Slackware 9.0) have anything to do with this?

check your media, make sure k3b supports 4x as well

Have you clicked on the bar that shows 1x and checked to see if there is a drop down menu that has 4x? If there is no option for anything else then you might try running k3bsetup again.

Yes, I know the media is 4x, because it came with the burner. Also, the dropdown menu only has Auto and 1x, thats how I know it only detects at 1x.

Is there a way to force the speed for DVD writing? Beause, I can adjust the burning speed of CD writing (because it burns at 40x, and it says that in the settings).

Or maybe does anybody know of another forum that is specific to my question? I've already tried hardware, and they didn't give me much help also.

maybe k3b does not support 4x dvd burning yet, did you rtfd?

what version of k3b?

did you try the k3b mailing list by chance?

did you try the forums for k3b on sourceforge?

i have found your answer in every one of my suggestons. i suggest you look around more

do it by hand
dvdrecord dev=0,0,0 -v -dao speed=4 image.iso

I didn't look in the forums of k3b because I didn't think it would help. Because k3b is just a utility to use with the dvd recording tools. So, if k3b is getting wrong information, I would think it would be caused by the dvd recording tools.

And because of that, I did go to the forums of the dvd recording tools to and there was nothing there about speed checks.

The version of k3b is 0.10.3, and the dvd rw tools is 5.13.4.7.4.

And also, reading from other sources, the speed= will only work with buring + medias and not - (or the other way around).
