Sounds like FTA is perfect for you. Being in the business, you know not to expect premium cable channels. There are tons of interesting feeds, and the AzBox will display 4:2:2. Many (most) other receivers will tune it and record it for playback on other devices, but will not display it themselves. Welcome to SatelliteGuys!
P.S. - I regularly watch the PBS network master feeds on 125W Ku as well as NBC on 103W Ku.
