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.
