On Friday(6-16-12) afternoon a half a dozen of the DTV channels had something sent to the receivers that put them on ch-3(or whatever). The receivers started the display "channel not purchased...." I've gotten 7 calls so far, and have talked them through the procedure to put the receivers back onto the proper channels. I called DTV and they said that they were receiving a lot of calls on this problem and were walking customers though the restoration protocols. I wonder what happened? Affected channels were HBO, ESPN, Nick, ect.
