I'm not sure about the takedowns video, but as far as leglocks, what I'd HIGHLY recommend is the Vincent Fields leglock DVD. It is 2 DVD's, has over 135 techniques that are shown in detail in 82 chapters. Overall it is 2 hours and 37 minutes of footage with no replays!
He shows all sorts of entries, setups, defenses, counters and re-counters of your opponents counter attacks from every position. I highly recommend it and sell the product on my website:
