Wes, thank you for posting about this and your experiences. Once I get my
system entirely automated I will then be able to make an assessment to
determine if your suggested modification to dvd-handler makes a difference.
Then we can compare notes. Hopefully other Bacula DVD proponents can also
consider this if they are having stability problems writing to DVD+RW.
Cheers,
