I'm planning on getting a pcHDTV-5500 to use with Mythtv. The problem is that in my building I don't get any cell phone reception, but just outside the door I get full service. Since the building blocks cell phone signal, will it also block OTA HDTV signals? I looked on antennaweb and I should be able to get the signals, provided the building allows. Also, I guess this card will allow me to view any unencrypted OTA signal, but not encrypted, right? Does antenna web tell whether channels are encrypted or not?
