Hi, if you are in the US, you need to create an account with
http://www.schedulesdirect.org this is a pay service that costs $20 US for the year. After creating an account and getting logged in, add your channel lineup information based on where you live, then after you have all the channels you want to view added/removed log out of your account, re-run setup wizard and when prompted during the "devices configured to receive broadcast media" screen, enter the e-mail address you used to create your schedulesdirect account, and the password you use to log in, it will then contact schedulesdirect, and get your program guide info, and then add it to the chosen tuner input. It will take about 10 minutes for mythfilldatabase to run, and then you will be ready to go.
Hope this helps.
Regards,
Seth
