as you can see in the example encoder, than bitrates are set to 0 the quality mode
is used. you should scale the video quality from 0-10(as the example
encoder does) and use the internal values from 0-63.

as just discussed on irc this is the *pixel* aspect ratio.
here is a nice table to get an idea of the mess.

if you do not want any scaling set it to 0:0
