Thank you VERY much! Set her TV set up, plugged in the mini box, and just like you stated, she gets all the lower channels. Didn't even need to TiVo to be powered up.
This is opposite the cable guy said when he first set us up. He had said that the little boxes had to get signal from the "main" box.. Thanks again!
