This past week the HD Tivo has been freezing and tonight it was unwatchable. It also freezes on regular SD channels, but not nearly as much. I don't have a multiswitch. I have the RG6 Quad cable coming straight off the LNB's to the Tivo. There is 2 barrel connectors outside, but they are under weatherproof cover and look fine. D* wants to charge me $70 for a service call. I've had every channel they offer for the last 6 years. Anyone have any suggestions as to what the problem might be?
