I know of about 15 or 20 digicipher (Not to be confused with FTA DVB) channels that you can receive free with a 920/922. The include numerous PBS, Bloomberg, Varsity TV/Canada, DMX audio (50+) and too many to name. Unlike DVB FTA you must subscribe to at least one C band service to unlock the receiver for the free channels. The best way to find the free NTSC analogue/Videocipher/Digicipher free channels that you can receive with your GI receiver is to check out Lyngsat (hope I spelled it right!). Good luck!
