OK, this seems strange but yesterday morning both of my H20 boxes were back to "ALL CHANNELS" instead of "FAVORITES" and the remotes didn't operate the H20 boxes at all. I have 2 H20's and a separate RC32RF for each box and neither one worked. Well after replacing batteries, rebooting the boxes and finally a call to D* and some putzing with them we finally determined that each box still worked if set to IR but will not work via RF. D* is sending out 2 new remotes but I think it likely that neither one will be any better. If a storm went thru is it possible that could have affected the RF capabilites of either the remotes or the H20's? BTW, IR sucks, why would the guide function different on IR than on RF?
