OK here's how I went about it:
I typed "screen recorder mac" into google and got all sorts of results, I used the first one I found. Saved the results as uncompressed video then loaded that into cs3 flash flv converter, from there I could do some simple editing and resizing. After which I loaded into flash with some flv repeat actionscript and dumped the rest on my server. They are in general about 2mb's big.
