AW: [mythtv-users] Archiving Shows to DVD

[Cory Papenfuss]

 	Sounds good that you've got something functional.  I've never 
tried to get mythburn to go as the requirements are a bit vague.  It's set 
up for knoppmyth, no?

 	Does it require the database to extract the cutlists?  I'm just 
thinking in terms of making maybe a partial script that can exist without 
the whole mythbox.  Just a .sql/nuv combo would be great.
