I'm pretty sure that's what's happening too. Starlight ran out of DVDs? We can just print more!
As for a fan-produced DVD, there just isn't enough footage available free-and-clear to mount such a project. Folks generally won't come forward because they don't want to get blacklisted from future Scott Bakula events by the people who run them.
My biggest QL regret is not having brought my video camera.

I figured
A) I wouldn't be allowed to set it up
B) The official event footage would be reasonably good
