this will actually degrade image quality cause divx fast motion (div4) has 
worse image quality for still scenes (then low motion -> DIV3) only helps for 
very high motion scenes.
Read more about this issue at the nicky guides, especially:

the idea with ripping is getting the best quality on a CD or two, so you rip 
to 650MB or 700MB or the double amont for 2CD rips. You can use bitrate 
calculators to esteminate the needed bitrate.
