Only bitrate reduces the file size.  I'd recommend bitrate of about 4500 
average/6000 max for 720x<height>.  See 
http://www.gossamer-threads.com/lists/mythtv/users/215461#215461 (and 
the linked tutorial) for more info and a nice graph (though the graph is 
assuming a pretty dirty source, it seems, as the bitrates are pretty 
conservative).
