Well, I've been reading some of the threads on new firmware and I am catching that if you turn to channel 499 it will let you know if your BBCs are installed ? I have HR20-700 with 0x18A...H20-100 and H20-600 with there latest. All have had the BBCs on the cable since install awhile back. Is tihs 499 channel check true for all Hx20s ? Out of curiosity what new "channels" will the BBC allow me to see that were not there before...I assume 499 is one. Thanks.
