Are you sure about that ? Yes, with a bitrate of 1200 Kbits/s it
probably doesn't make a large difference, but with more reasonable
bitrates (to store an entiere film on a 700 MB CD) a 2-pass or 3-pass
will improve things. Or am I mistaken ?

In fact the answer is probably codec-dependent. What about xvid
instead of lavc ? (can't really check right now as it seems xvid
cvs-current is seriously broken).
