One more question - in using these settings (min 4 max 16 quality 60%) and intending to author an animation to DVD what would be the vertical resolution to use? This will not be High Def but rather shown on a DVD player with hdmi in standard 480P upconverted to 720P.  

The reason I am asking is that if I use 720 - it looks okay but has artifacting and some fuzziness. It gets better when I go to 960 and even better at 1080 vertical resolution.   I don't know if I am overkilling this going above 720.  I just want it to be the best for what the eye can see and not take a millenium to render.   Any suggestion would be appreciated from your experiences on this....
