I am using VirtualDub to output compressed AVI files from input JPG files. I choose
Full Processing Mode
as the video mode and
Códec Cinepak de Radius
I chose image quality of 100%, 50% and 10% but the output files are all the same size. I would have expected the lower quality setting to produce smaller files. Am I using it incorrectly?

Cinepack is an horrible codec, and, as Roman said, it don't appears to really have an quality setting.
I suggest you to install the Xvid version 1.3.2 codec and try again. There are many tutorials on the internet on how to use it (although most of them are pre-2006/pre-x264). Here is a simple and up to date one: http://granjow.net/virtualdub-tutorial-installing.html
Also, if you are not using VirtualDub's filters and such, you should use "Fast Recompress" for the video. It is a little bit faster and higher quality, as it don't convert the color space of your picture from YV12 to RGB and then back to YV12.
IIRC, "Cinepak Codec by Radius" does not have a quality setting. At the very least the underlying VFW/ICM codec does not show a quality slider as an option. I suppose VirtualDub's setting is just ignored.
