Thinking about getting an HR-20. Right now I have OTA locals direct to my Samsung DLP. I live in area with acceptable but attentuated signal strength due to a mountain/ridge in the line of sight to the stations 20 miles away. Using a channel master 4228 antenna. (Analog signals have always been a bit snowy here.) How good is the HR-20's tuner a picking up signals compared to most current HDTVs' tuners? Anyone had sucess or problems tuning stations with the HR-20 compared to direct to their TV set?
