is there a way to plug my antenna into my DirecTV HR22 DVR and record OTA channels? There's some shows (Jeopardy!) on out of market channels in HD that are only in SD on the in market channels available on DirecTV. So is this possible? The HR22 has a second coax input labeled "sat 2", could I use that input somehow to do this? Would the box be abel to read the OTA signal and program data, etc?
