I can't pick up a lot of my 200 HD channels here in Sault Ste Marie Ontario . happened yesterday Oct. 2nd during the Blue Jays game. message says" lost of signal or not broadcasting at this time". had to switch over to channel 18 to watch the rest of the game I get this message on my movie channels and HBO and a lot of others also. All the lower channels are ok but not the HD ones. I have the gateway system with 2 portals and the same thing is happening on both TVs. any ideas as to what's happening?
