I have DirecTV and I have been planning to put up another dish and buy the Hughes Platinum HD set top box. The question I've been asking myself lately is, "Which is better, HD off of a set top box utilizing the satellite feed or a HD card in my HTPC tapping into the OTA signals" Now obviously since the latter is literally 'over the air' there are some tuning issues potentially. However, is there any conventional wisdom concerning which is actually superior? I've heard OTA is superior to the HD signal that you get through DirecTV. Any thoughts?
