Why can my TV receive all the OTA digital channels and my Tivo Premier can't?

    I don't have a subscription with Time Warner but I can plug the cable wire in from the wall to my TV and get all the OTA channels with no problem. But once I plug it into my Tivo, I only get about 6 channels versus the 20+ that I get with plugging it into my TV.

    What gives?

    Are you doing a channel search on the Tivo when you connect the cable?

    Yup. And when I do the channel search, it brings up many channels but once I flip to that channel, it says "Searching for signal on this channel"

    Could be the tuner in your TV is more sensitive than the tuner in the Tivo.

    Also, there are many claims on this forum that the tuners in the Premiere line have been the weakest, when compared to the Series 3 and Roamio lines. IOW, TiVo chose to cheap out on the tuners they put in the Premiere.

    This doesn't sound like a tuner sensitivity issue to me. When the OP says he doesn't subscribe to TWC but gets signals when he plugs the cable in, I assume he means a signal from TWC, not from an antenna.

    I'm assuming it's a mapping issue??

    I thought it was clear that the OP is talking about the clear QAM version of the OTA channels. Obviously they are not mapped, but everything his tv receives should be received on the Tivo and on the same channels.

    Not if he's using a digital only Tivo and his local TWC is still sending out some analog channels...

    True. It's easy to forget about analog when you don't have it.

    So, Gifted1, which Premiere model do you have?

    He can't have a card, he doesn't sub to TWC. He's just trying to bootleg clear QAM. It's not uncommon that some tuners pick up all the clear QAM channels fine and others don't though.

    Interesting, did not know that. I assumed sensitivity to picking up channels only applied to OTA.

    Why does it happen on clear QAM?? Certainly it's a good strong signal.

    Maybe not. Cable companies usually put a blocking filter in line at a location that does not subscribe for service.
    Could be a situation where the filter does not cover the whole spectrum or is faulty in some way.
