Try searching on http://creativecommons.org/video/ or
http://search.creativecommons.org
If you are ok with recompression, there are things like this (89
minutes):
http://www.archive.org/details/panorama_ephemera2004

I would assume that the authors of videos under CC will be also more
open to give you an exception to share-alike clause for the case of
papers and presentations (although there is a good chance that this kind
of use is exempt from requiring author's permission - check the
respective copyright laws and/or ask a lawyer).

Good luck in your research!
