I'm running OpenSuse 10.2 on one of my desktops, which also has a dvd writer.
Lately, whenever I burn a data DVD with K3B, the program goes through all the motions as if it's correctly burning and verifying the DVD. Yet when I examine the disk that's been burned, Konqueror tells me the disk I just burned is blank.

Bob I would personally use K3b to build an ISO image but use wodim/growisofs to burn it, for some reason K3b is not entirely sane in interaction with this new set of tools.
Not heard of that problem on any other list. Can't deny it maybe your experience, but I think you describe personal preference rather than genuine fault with k3b.
When wodim rather than cdrecord was adopted quite a few people had problem with wodim and K3b... Some re-installed the original cdrecord software to deal with the problems that they had with the wodim/K3b combination ... K3b has been unreliable for me for quite some time for the actual burning process ( I have been working on some perl stuff which seems to promising for managing wodim/mount/growisofs to burn data without too much grief)....
DVD-R is the least data friendly of the DVD formats, DVD+R and DVD+RW are more reliable in my experience.
Again personal preference not fact. I and others on other lists have found the opposite - DVD+R just won't work on my systems - laptop and desktop.
Read carefully "least" does not mean not... these are hardware restrictions not media restrictions...
DVD-R is really more aimed at multimedia use...
It's a myth that one media suits music, another data, another video. Data is data. DVD-R is probably the most compatible format for all types of hardware because I believe it's older than the others by about 5 years. Therefore, s/ware and h/ware has had more time to learn about DVD-R.
There are some significant differences in the low level structure which make DVD-R a little less suitable for Data usage... (though to what extent this is FUD from the DVD+R camp is a moot point)... I did spend some time looking into this. I refer you to the article below as a starting point.... http://www.cdfreaks.com/reviews/Why-DVDRW-is-superior-to-DVD-RW there is also some interesting data on the DVD+RW alliance site on this. http://www.dvdrw.com/information/DVDRW_Physical_Format_Explanation.pdf
Try burning an image with growisofs from the command line and take note any messages (to avoid more coasters, use RW format for the test :-) )...
Good advice for fault-finding. The only time I have had the 'coaster' experience described by the OP was when the media was no good. Change brands of dvd disc and definitely avoid 'no-name' cheap discs - they're false economy.
Agreed...
Gavin.
