Advertisements Hi there all! I have a TIVO Premiere Model TCD746500 with a lifetime sub. My question for those on here is that I only use it with OTA signals which because of location are weak. I'm reaching out for feedback as when the antenna is plugged into the TIVO, I only get 2 channels. Yet, when the same cable is moved from the TIVO to a Samsung TV, I get a whole array of channels. I was told by a store that mainly supplies OTA equipment that the TIVO channel sensitivity is very poor and that's why my situation. I'm trying to find out if that is the case and also if changing to a newer TIVO unit has better electronics in it that would allow me to record these other channels that my TV receives. I'm thinking that the newer units with 4 tuners would even further split the signal to service the 4 tuners, thereby getting a less than desirable outcome after having paid out for a new unit. Any comments would be well appreciated! Thanks!
