Agreed. But my point is: what’s the cost of the mistake? In my 
experience so far, it’s only taken a few minutes to re-author a 
DVD-Video directory structure (the time-consuming part being, of course, 
the conversion of the video to the right input format). So you 
accidentally blow it away, it just takes a few more minutes to get it 
back again.

And are you really going to do anything intricate just with a sequence 
of interactive commands? For myself, if I’m doing anything remotely 
complicated, I’m going to save it in a file. In the case of DVDAuthor, 
that means an XML file, I’ve never even bothered to understand all the 
options for building the structure directly from the command line.

Yeah, I think that’s a reasonable alternative.
