I think the TiVo is doing a fine job of that!

My DVR didn't pick up the Lost 8-9 recap show when it usually does. When they ad the pop-ups they give it a new code so that DVRs will pick them up. A sneeky way to try to get us to watch repeats and bump up their ratings. But this time I had to manually add it. And it recorded the two hours just fine. (I have the digital DVR from Time Warner).
