Thanks Brian, I see a lot of the CC BY-SA and it seems the closest to Open Source copyleft for non-software. BY looks closest to a liberal, BSD style licence. PD means you effectively waive all copyright and any one can do anything with and I would usually prefer something that keeps works in the public 'commons' . However as the important thing is to spread the word PD is probably OK.
It would be fine to also use the following: Creative Commons Attribution-Share Alike 3.0 Unported License. The advantage of this license is that the "Share Alike" ensures that any changes made to the video remain with the same license. But, a simple public domain license would probably also be fine. Brian
