[MPlayer-users] mencoder dv to avi using h263

I need to turn raw dv files into avi using a H-263 codec, for a Java project. (Unless someone has a better idea for generating files that JMF can read.)
So I tried this (yeah, probably stupid):

mencoder test.dv -o anvil/test.avi -ovc lavc -lavcopts vcodec=h263p -oac copy

MEncoder 1.0pre2-3.3.2 (C) 2000-2003 MPlayer Team

This is a plain, raw dv file generated with dvgrab --format raw. 

How can I encode it with an H-263 codec?

Cheers,
David
