So my S3 is all hooked up to the cable feed, waiting for the Comcast guy to show up next week with my cablecards. But I've got no HD channels in the meantime, so I hit on the bright idea of running the channel scan to see if the HD locals show up in the clear and low and behold there they all are, like Fox is on 2-1 in great quality, easily as good as it would be on 702 if I had my cable cards. Trouble is, TiVo won't supply guide data for it, won't admit the channel is Fox, keeps putting its hands over its ears and saying "I'm not listening" etc. Yeah I know, this is in the FAQ - QAM-in-the-clear is half supported, no guide data, yada yada yada. Then I tried splitting my cable feed (already had it through a splitting amp anyway) feeding the copy into the antenna input, then redoing guided setup for cable and antenna. My theory was that it would find channels like 2-1 on the antenna input in the course of the scan. Turns out that doesn't work though. Damn. Must be that only ATSC channels are looked for on that input. So here's my plea. Please TiVo, make digital local channels work. It gives multiple HD channels that work even if your cable card is missing or on the fritz. Some people wouldn't even need to get cable cards, if all they want is HD locals and analog cable.
