About 11years go my wife was going to make a porn web site then changed her mind. The person that did the shoots has no model release or contract.

There is good news and bad news. The bad news is that the creator of a "work of authorship," like a photograph or video, is the owner of the copyright in the work - even if you paid for it. While there are exceptions to this, from the facts you stated it does not sound as if they would apply. Regardless, unless your wife was the photographer's employee (which I don't think from what you say is the case), you would have to have a written agreement with the photographer for you to own the rights in the photographs/videos. However, while you may not own the copyright in the photographs/videos, the good news is that photographer may be limited by your wife's "right of publicity" from using photographs/videos with her image for commercial purposes without her authorization. The "right of publicity" varies from state to state so you need to consult an attorney in your state (or wherever he is threatening to use them) to see if your wife can prevent this use. You may have another problem, however, which is the statute of limitations. You say that he put the DVD out in 2005, so you waited 7 years to complain. You will have to find a state with favorable right of publicity laws where the statute of limitations has not run.
