To purchase a NASA video, contact CORE. If you have the ability to copy them yourself, since all NASA films are public domain, you can borrow titles from Media Services Corporation at the Johnson Space Center. A couple of NASA video catalogs are available online.
For Earth-science-related videos, there's no place better than USGS's library in Menlo Park California. Many videos are public domain, so you can copy them yourself. Call Mike Moore at 415-329-5009.
