Since I use 700MB CDROMs, I first calculate the framerate needed to fit on this media type.
Simplest way to calculate is let mencoder do it by stripping out the audio track. Since this is of fixed size, subtracting the size of the audio track from the size of the media. The remainder is the size of the video you can fit.
