I understand, Elainea717! If you have a Hopper or Wally box, you can set the preference for what you see when starting up the box under the Power Settings. The choices are "Tune To Last Channel", "Show Home Screen", or "Tune To Smart Channel" (which is based what's popular at the moment, or previous viewing history).
View the instructions here, and click Power Settings: https://www.mydish.com/support/products/hopper/how-to/set-preferences/set-display
Hey, Williamhill! We don't have a way to stop the Recall button from performing, but, if you have our Hopper system, you can have the Recall button perform a different recall function such as Tune to the Last Channel, Show the Last 6 Channels, or Tune to the Last Channel while showing the last 6 channels.
