If I'm not mistaken, access to these videos previously required an account from a GV-funded company. It looks like they've opened up content to everyone. Very cool.
I tried the "request access" option on a movie I wanted to see (Effective Story Telling). Hope the author grants me access.
BTW, when I worked at Google as a contractor, I had to request access to many papers I wanted to read that by default were just available to employees. Almost always the author/owner would grant access.
