This post from Law Meme describes the narrowing of DirecTV's anti-piracy efforts, while this article from law.com describes the 11th circuit's ruling against DirecTV in one of the first of the cases to go up on appeal.
The Eleventh Circuit's opinion in DirecTV, Inc. v. Treworgy is here.
In DirecTV v. Adkins, Judge Jones of the W.D. Va. did not need to reach the issue decided by the Eleventh Circuit regarding a private cause of action under the Electronic Communications Privacy Act, granting relief instead under the Federal Communications Act, 47 U.S.C. 605.
