You can put the Hopper in standby (turn it off) and leave the TV on to watch the screensaver. After many minutes, you should see a guide download start with a percentage progress indicated. Watch that percentage carefully. It may go back to the regular screensaver in the middle of the download, making it look like it is done, but it is not. After waiting some more minutes, the guide download screen will reappear. When the percentage indicated reaches 95%, then the next time the screen goes back to the screensaver, the guide download is actually done. You can then turn on the Hopper and go to the guide to see the guide information populate for the OTA channels. Dish may not actually provide OTA guide data for all of those channels. However, the ones without guide data will display one-hour blocks of the station's call letters, making it easier to set manual timers for those channels by selecting that block in the guide.
