well divx uses a variable bitrate yes, but you can still get an accurate 
approximation. i use that simple equation, and using abr on mp3 my files 
are nearly *always* 683 to 686 megabytes. works great, however approximate 
it might be.

good for you. i still say calculations are fine, assuming you can make 
reasonable assumptions about the source video.
