Both videos have been pulled from Youtube.
That's weird. I just checked and both were there. It would be a shame to pull them. There were some interesting parts in them.
For example, in the second vid, I liked (near the end) where he was showing a Daito ryu technique that looked like what Takeda was famous for (getting in and lifting someone on his shoulders) and how it was changed to the aikido version (kokyu nage technique for some schools).
