Advertisements Today I gave my son his own TiVo. Not that big of a deal. He's had his own Tv in his bedroom for awhile now. Anyway, I hooked his TiVo set up using the RF cable in and out - no cable box. I hook his DVD/VCR player up using the RCA leads to the Tv set, input 1. I set the channel lock by allowing the Tv to redo channel search. After it locks into channel 3 I disconnect the cable feed in to the Tv - thus allowing it to only lock on channel 3 - I allow it to run up to channel 99 - thinking that it would be over I started to hook up the RF cable and it jumped to 100, 101, >>> 124, 125. I've always know that most Tv sets go up to 125 channels. I have just been so use to the cable only TiVo stopping at 99 channels. I just thought it was a little odd, like a 23 channel CB radio. So the question is... Why does my son's Tv set from 1990 go up to 125 cable ready channels and the TiVo from 2005 only go to 99 channels? Why not to 125? Why does the Tv not stop at 99? Not really that important - just curious.
