I get the dreaded "One moment please this channel should be available shortly" message on about 14 of my channels about 75% of the time. We have 4 TVs in the house, 3 are connected by coaxial directly to the outlet and 1 is connected to a cable box to get the guide and about 15-20 extra channels. The only one we have the reception problem with is the one with the box. Have checked connections and changed cables to no avail. Most of the "problem channels" are not the extra ones, so fortunately we can go to the basement or bedroom to watch a show we are missing. Any ideas?
