Can't burn DVD's with k3b or Gnomebaker

[Linshark11]

Hello!

I can format a DVD-RW with no problems, but I can't
burn anything. I get the same input/output error in
k3b and Gnomebaker. What could be wrong ?

Fedora Core 4 with lots of updates.

From k3b:

:-[ WRITE@LBA=0h failed with SK=5h/ASC=64h/ACQ=00h]: Input/output error
:-( attempt to re-run with -dvd-compat -dvd-compat to engage DAO or apply full blanking procedure
:-( write failed: Input/output error

thx.
Martin.

same problem here, only when I use CD+R CD+RW it works as expected. k3b only gives an error on growisofs did not exit cleanly on DVD-RW. And I need DVD-RW to be able to watch my movies. xine seems to play only + cd's. My dvdwriter does write dvd-r an -rw, so that is not the problem. I will appreciate any suggestion very much.
