Here's a video that gives an overview of new video coming out called "SAS Fight Secrets". It's taught by Bob Spours, former member of the SAS (the British version of the Special Forces). The video looks very good and cut through the crap to give you just a handful of techniques to get the job done. The only leg techniques that it appears he teaches is knee techniques, which I guess is because your body isn't as "off balance" when throwing a knee (you are usually hanging onto your attacker) as opposed to a kick. Anyway, here's the link:
