I bought a Samsung SIR-T160 on Ebay. I have no intent of getting DirecTV. I want to use it to tune in OTA HD and regular NTSC over cable because I have a projector so I need a tuner to even watch regular TV. I cannot get through the setup without an access card. What do I need if I'm never going to use DirecTV or did I totally screw up on my purchase? There are P4 and P5 access cards on ebay as well (some say "only tunes in the demo channel"). I've been told that I can go and set my "dish type" to none, but I'm getting an error that there is no access card. Will one of these cards get me through setup to tell it that I have no dish or not?
