I think what happened was you asked it to pack too much in. The 
shrinking function (tcrequant) can only shrink by a 2:1 factor as a 
maximum. Dedending on bitrate you recorded at each of your movies could 
be 4GB or more so its possible that you just asked too much. For me a 2 
hour movie after processing turns into almost a 6GB group of files which 
then shrinks down to 4.5GB for the dvd file. Try a single movie and the 
autostart menu for a quick and dirty test.
