Joe,
I still have no new info about copyright/registration of my commercial, but I did receive some feedback from Pond 5, (yes, that’s the company I’m using too), regarding the clause of the license agreement that you cited, and I thought you might find it useful.
“The clause about the Licensee providing access to no more than 10 Authorized Users, is referring to access to our raw, unmanipulated content that you download from Pond5. That clause is to prohibit buyers from uploading content to an office intranet to make it available to everyone in the same company.
The work that you create with the Pond5 content, which is the “Work for Distribution”, may be distributed as widely as you wish, and can be viewed and sold as part of a “work for distribution” an unlimited number of times. “
Thanks,
Tom Raymond
