They have been pretty active about having it removed. I purchased it several years ago from Dyens' site (in a PAL format that I needed to convert).
I received a nice letter thanking me for actually paying for it, and asking me not to share it.
I suppose the videos may have gotten more attention lately, so perhaps they are being even more vigilant at the moment. I'm sure every time one is taken down ten more pop up though.
It's a wonderful video and well worth the purchase. I know SBM sells it, and it looks like there are some sellers on AMZN too.
