I haven't tested this on ubuntu yet, but it was working fine under
CentOS and doesn't care what the OS is as long as you have mplayer and
mencoder installed.  This should work - tweak to suit your
sensibilities.  It will play the video once to detect the actual frame
size, allow you to change it and then plays it again for your approval
(you don't have to watch the whole thing for this).  My only annoyance
is that it takes a long time to perform, but the results are usually
pretty good, better than I got with DVD::rip.

(Note: if any of the lines below wraps, just sew them back together in
your editor - it's not too hard to tell if this happens.)
