Hey Gdjordahl! Let's take a look and see what's causing this to happen. Is this the first time your timers did not show up in your DVR schedule? We want to first confirm no hard drive errors have occurred.
To check for hard drive errors please press the MENU button twice or the HOME button 3 times at the Hopper remote. This should bring you into the Diagnostics Screen. Arrow down and select "Status" then arrow across and select "Check Status". Finally select "Yes" to begin the test.
Let me know what display's in box "D" after the test.
