Your best bet is go to a tech forum and seek an answer there.
I am sure someone has had the same problem.
Unless Favre's spectacular pay blew up your DVR.
My guess is he exceeded the recording limits of his DVR assuming he was recording it via DISH Network or DirectTV. With DISH I believe it's 60 hours of record time.
Or he forgot to pay his bill.
Dish doesn't restrict you.
The only restriction you have is the size of the hard drive.
If you use up all the room, it will start taping over old recorded material, starting with the oldest.
Found that out the hard way during the Bejing Olympics, when I accidently erased ALL of my wife's sitcoms... :)
