 	Likely because a remux is necessary to burn to DVD.  A standard 
ivtv stream contains only video and audio.  Burning to DVD requires blank 
VOBU packets every so often so dvdauthor can put the necessary info there. 
Tools such as replex and dvb-mplex are able to do this on the fly, but 
without those two, the only way has been to strip A and V, and then remux 
with padding of the VOBU stream (e.g. 'mplex -f8 ...')

 	Or qdvdauthor.  I haven't compared in a few months, but at that 
type I found qdvdauthor to be less unstable and more functional.  (note I 
didn't say more stable).
