Add vbitrate to the lavc options. The default is quite low (800Kb), try at leas 
1200. Also check all the other quality enhancing options for lavc and use 2 pass
encoding.
Take a look to the mencoder documentation or on my page i have an old, but 
still valid summary of exactly your problem (www.cscs.ch/~mvalle/mencoder/)
