[MPlayer-users] How do I get a decent sized .avi file using mencoder?

[Austin Gonyou]

When enconding a DVD to AVI(DivX5), I can see the VOB on the disc at
1gb, but after encoding, my .avi is about 2.2gb. Yet, I changed the
aspect to be smaller, and also used a low bitrate, say, about 1800, or
even 1000. 

I figure those two things right there would make a difference, but I
can't seem to figure it out. Any tips on this would be great.

AMD Athlon-C 1.333
512MB DDR 266
40GB ATA100 IBM
Cheapo DVD from Fry's. 

mencoder -dvd 1 -alang en  -ovc divx4 -divx4opts  br=1600 -pass 1
-aspect 640:400 -o somefile.avi

TIA
