Ok, I also just joined this group to find some info on 4Square.  I finally found some DVD's from Treehouse Direct.  If you google it and play around on the site, you finally come to a spot where you can by sections of the show for $1.49 each.  You have to download Treehouse Direct though in order to buy.  Other then that I haven't been able to find them anywhere.  We should start a business.

 

Good luck to you all in your hunt.  I hope this helps.
