Just got mine installed last night, bought it from onecall. Excellent unit. I like the interface very much. The two HDTV Directv channels are very good, the loop on 199 utterly spectacular in parts, almost 3D in its effect. No over the air yet, still experimenting with indoor antennas (Silver Sensor does not work). Wife won't allow outdoor and there is a hill just in front of my house so I don't have line of sight to Mt. Wilson. I have a Stealthtnenna that I'll try today, then I'll try the Rat Shack bow-tie, and if those don't work I'll probably give up.
