Dear Gray

Did you post the following message to the bug tracker and sent me a 
copy, or did you only post to me? I ask this because there are little I 
can help on technical issues, you will have more luck on forums or bug 
trackers. I am always confused about burning stuff and my only way to 
help the community is to complain to them:)

please do try to post this message on debian cdwriter mailing list.

http://lists.debian.org/cdwrite/

As that is the single most helpful mailing list on DVD/CD burning issue 
there. Someone there answers question in surprising accuracy, once you 
do you know what I mean:)

Best.
