record is unavailable message - DirecTV

I missed an episode of a tv show I want to watch from 1 week ago. When I try to watch it, I get the message oon the screen that "Record is unavailable". This happens on al;l tv show episodes shown on my computer screen except for House which tells me I do not have the correct receiver. My receiver is H21-200 whic h I have had for several years. Please help me to resolve the problem, I can stream live tv programs.

This question, "record is unavailable message," is about DirecTV channels, programming, equipment, and sports.
