Advertisements Hey there. I’ve read a bunch of stuff that is confusing about what this may be so I am opening a new thread and hoping somebody can give me some clear guidance. Our TiVo is not connected to an antenna. We haven’t had an issue getting over the air channels in the past except occasionally. However, a number of our channels disappeared. I did the rescan and the channel still don’t work, even though they worked within the last month. Any ideas would be greatly appreciated. My almost 80-year-old father is coming to visit and he loves one of the old rerun channels that stopped working.
