I ought to add that the sequence above is pretty much what mytharchive 
would do - but if something goes wrong all you can do is try again.  The 
transcode-from-HD step is slow, and a failed dvd burn isn't useful. 
Working in stages lets you keep track of what is happening and retry if 
appropriate.
