My apologies if this didn't split the lines properly. When I got the
message, the split in the two lines came out wrong, but in the reply, they
came out right. Anyway, this is what it should look like:

mencoder infile.mpg -o /dev/null -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=1100:mbd=2:vpass=1:vqmin=2:vqmax=31 -oac copy

mencoder infile.mpg -o outfile.avi -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=1100:mbd=2:vpass=2:vqmin=2:vqmax=31 -oac copy
