Ogg file too big, where did I go wrong?

I tried to make a 700 MB rip using DivX 5 for video and Vorbis for audio. The final file is 703 MB, 3 MB too big! I used gknot for calculations: Audio file = 46 MB Overhead (just avi checked) = 4 MB Video = 650 MB Now I encode the video and I get an avi that is 654 MB (686,381,056 bytes). When I use OggMux to mux the avi & the audio with chapters, the final ogm file is 703 MB, 737,665,671 bytes. Can anyone give me any insight as to where I went wrong? I'm guessing that it has something to do with the muxing of different containers. If anyone could point me to some literature about how the overhead and stuff works that would be great. When an avi is muxed into an ogg format, are the avi headers (overhead) removed and then the ogg overhead added? When you mux a whole bunch of stuff together is there additional overhead on the file, or are the data steams all stripped from their containers and then added all back into one container? Any insight would be great, I'm trying to figure it out.

Well, in case the picture doesn't speak for itself, you can try this as well:

LOL, LOL :D :D :D

we should definitely get a smiley for this :D
