Gutsy won't recognise a blank DVD

1. It might be a bad disk - try another.
2. Run K3B from the konsole, perhaps it will produce extra info.
3. Run "dmesg" from konsole, look for error messages.
4. There are other tools to try manual burning, but that's such an arcane art 
I fear for my sanity in cracking open my notes. But, it does produce a lot of 
info about what's going on. mkisofs and dvd+rw-format are a start.

I hate it when random stuff like this happens, but it never looks so bad after 
the problem is found, so just keep hacking.
