No, I leave the Dish's Update feature (Menu/Preferences/Update) on it's default setting which is enabled to activate at 3:00 am. This turns the receiver off so that program guide information can download. This will leave the unit off until you turn it back on. So, this is why I create a timer (menu/timers/create timer) to have the unit turn on at 4:58 am, however, you can set this timer to whatever you want. This gives me the freedom of knowing that basically from 5 am to 3 am my replay will be able to successfully record any program without accidentally encountering the screen saver, and yet, the receiver can still perform it's daily program guide updates.
BTW, in the steps to setting up the timer to turn the receiver back on, I mentioned I choose the setting 9901-D1000. This turns the unit on to channel 9901. This channel is just a screen that says, "Congratulations, you have a Dish 1000 System". It doesn't matter because the Replay's IR Blaster will now be able to change the channel to whatever I've asked it to record. I hope this helps clarify.
