Hi,

for completion, could you please provide us the version of ubuntu and the version of the dvd+rw-format package?

Suman

[suman (schakrava)]

Hi let me be more clear. you can find the ubuntu version in /etc/lsb-release file. secondly, dvd+rw-format is part of dvd+rw-tools package. you can find the version of that package with "dpkg -l dvd+rw-tools" commands. you may already know this, but just in case.

Suman.
