Actually, the man page DOESN'T suggest using this buffer size. It does,
however, inform you that it's needed for encoding *TO* DVD (i.e., making
your own DVDs). Maybe the man page wasn't entirely clear on this point.
I'd also like to point out that you're setting quite a few options to
their defaults. All of the following are already defaults, and don't
need to be set:
So out of 20 lavcopts, you're using 9 that have absolutely no effect.
May I suggest that you check out this document:
Sadly, every other mencoder guide on the web totally sucks except for
this one. Try reading section 7.11.6. Hopefully this will help some.
Finally, I agree with ZikZak's excellent advice: use the turbo option
on the first pass.
