I have two DVRs each in a separate room. Issue 1: When watch show in the room where DVR #1 is located, the show will jump 2-3 minutes to the end of the show immediately following FF through commercials. I stop the FF just as the commercial ends, but the DVR proceeds to the end of the show without me being able to view it. I then have to FF all the way through the show and watch the last series of commercials be able to see the end of the show. I have two DVRs. Technicians tell me the speed in the cables insie the house as adequate. Please help;
