My DVD writer is a NEC DVD_RW ND-6750A, system is Jaunty i386. These are 
my test results with the k3b version from the ppa 

* New data project.

I added one file to the project and try to start burning to a non-empty 
DVD+RW (with udf data on it). Error messages:

[x] can't open for write
(i) it may take some time to empty the cache
[x] :-( /dev/sr0:304 doesn't look like isofs!

where [x] is a white cross in a red square and (i) is a white "i" in a 
blue circle. BTW: the first 2 lines are my translation from German.

This is the end of ~/.kde/share/apps/k3b/lastlog.log:

There seems to be a problem detecting the right multi session mode 
because when I selected "no multisession" or "start multi session" 
instead of "automatic" or the other modes I could burn the dvd OK.

However after burning the dvd, k3b died when it should have verified the 
data (if I don't select verify k3b does stay alive). This is the end of 
~/.kde/share/apps/k3b/lastlog.log after k3b died:

I couldn't find any other file with possible information about the 

* Erase CD-RW: OK.

* Write ISO image to CD-RW:

After selecting the image file (xubuntu image) there is an error 
message "md5-sum: calculation failed" (my translation).

Burning is OK without verify, k3b dies after burning OK when it should 
verify the data (see above).

* New Audio CD (medium = CD-RW):

When the burning procedure is started, there are 2 wodim processes but 
nothing happens (no I/O activity) even after 1/4 hour. Only if I select 
to create an image, it works and the audio CD is burned OK.
