embedded political video keeps changing every few weeks

Two videos I’ve embedded keep changing. I’ve re-found & re-embedded it each time. One video went from:

&m=628395
.. to ..
&m=639643
.. and recently to ..
&m=653712

Each time the video changes, a new clip I’ve never seen is embedded instead – I don’t get “This video is no longer available” or anything to that effect.

The clips I’m embedding are political in nature (one is Matt Damon criticizing Sarah Palin). Is the changing video normal, or is someone at Voxant letting their evil Republican tendencies harm their job security?

(Anyone else experience this issue or know what’s going on?)
Thanks
