For a general-purpose DVD rip, vbitrate=4800 is really high. 800 to 1000
should still give you near-DVD quality.
I don't know if it matters, but the documented syntax for scale is
scale=width:height. The filter seems to work either way, though.
Also, in my experience it is better to use -ofps 23.976 when ripping
most DVDs. If mencoder gives you a lot of duplicate frame messages,
almost definitely do this. Search google for telecine or 3:2 pulldown if
you're curious.
