At 4am CDT this morning my TiVo HD was recording a show I had requested and it was also recording a TiVo ad on the other tuner. When I tried to switch to another channel, I was prompted if I wanted to stop MY recording. I haven't been up early enough to run into this in a long time, but TiVo used to stop its own recording without even asking when you wanted to switch the tuner to another channel. I tried recording two channels myself, but it simply ignored the request to record the second program. Is this "TiVo ads have priority" scheme something new.
