Watching Previous Episodes on DIRECTV - DirecTV

When I search for a tv show and it presents me with the various episodes available on DIRECTV (not the whole series, just what is on DIRECTV), I can click on the old episodes and read the info but not watch them. My only option is to record future episodes. It used to be that I could watch anything that was displayed. Now I can't watch anything on demand. Has something changed? Do I need a reset?

This question, "Watching Previous Episodes on DIRECTV," is about DirecTV channels, programming, equipment, and sports.
