I'm no expert on the subject, but I would think there are laws/restrictions against doing that very thing. Sounds like a copyright infringement, at the very least.

Watermarking is a security feature and is used to prevent the type of activity you are attempting. If you have a legitimate right to edit the video, contact the appropriate person and plead your case.
