replace vhq with mbd=2 for starters, and use two pass mode...

If you've got patience to wait, add atleast trell to the lavcopts.
trell:cbp:qprd seems to increase quality for me, but that's on 
non-animated source. 

Is your source material really interlaced? Telecined? I've never encoded 
such material myself, most of my DVDs are 25fps progressive afaik, so 
can't help you there unfortunately :-\

1000 is too low a bitrate for full DVD resolution, you want to crop out 
black borders and scale down to a multiple of 16. TOOLS/calcbpp.pl 
might be of help, as well as DOCS/tech/encoding-tips.txt

Variable bitrate as in vqscale=2?
