I have an outdoor antenna. When I plug it in to my TV, I get every single channel and the signal strength for all channels is around 90%. But when I plug it in to the Tivo, some channels will be tiled sometimes and wont come in clear. I have a splitter and plug one cable into the TV and one into the Tivo so that when a channel I am watching is acting up, I will just switch the source to TV and watch it clear. I know there is an issue with the Tivo's and that is why this is happening. My question is... is there any fix for this? Would an amplifier work? Anything else?
