If you have Tivo and just got a dish satellite receiver installed, then you MUST unselect any channels you don't subscribe to under the Tivo settings, otherwise when you select a channel you don't subscribe to with your Tivo remote, it will lock up the dish and give you a message Attention 013. You will not be able to view any channels after that without the message, even ones you do subscribe to, until you find your Dish remote and use it. The reason, I think, is because the error requires a response from your Dish remote which your Tivo remote can't perform. Once I unselected all of the channels I don't subscribe to under the Tivo settings, the problem went away. Good luck, Dish tech support didn't know this answer.
