I agree with Mr. Whitaker. Also, the attached link may be helpful to you.
Please do not consider this answer legal advice. My answer is for informational purposes only. You should contact your attorney to obtain advice with respect to any particular issue or problem. The answer does not create an attorney-client relationship or privilege.

Unless the cable company will serve as a middleman you need a representative to write Copyright Infringement, LLC if you want to settle and remain anonymous. That needs to be done by someone who knows the legal ramifications of each word used in writing them. That means an attorney.
Most settlers take the gamble, write direct, and rely on Copyright Infringement, LLC not to welch on the deal. I am not aware of any reported incidents of them welching by raising the settlement figure once they give it. If anyone has, let us know.
So far, this is free to you. Until you pay a fee, I am not your lawyer and you are not my client, so you take any free advice at your sole risk. I am licensed in IL, MO, TX and am a Reg. Pat. Atty. so advice in any other jurisdiction is general advice and should be confirmed with an attorney licensed in that jurisdiction.
