I apologize if this has already been answered. I looked, but couldn't see this exact question anywhere. I just bought an h20-600 to use it's OTA tuner. I went through the setup, and of course it found no satellite, but I continued, and when it asked for a zip for local OTA, it thought for awhile, then said invalid zip. I exited setup, then manually had it scan for channels. It found all the ones it should have, and the picture looked good, but it popped up a box saying I needed to insert an access card. I can flip channels, but the insert access card message is always on top of the picture. Is there any way to turn that off? I don't have, and thought I wouldn't need an access card, since I am only interested the OTA programming. Thanks a ton.!
