While I was watching (live) a game on MLB Network HD, TiVo popped up a warning message saying "Press Select or this channel may be temporarily unavoidable". Why am I getting this message? Blacking out a channel I'm watching live is outrageous. This would be especially bad if I were recording a game, then I wouldn't be around to stop the channel from blacking out. I've seen other odd behavior from MLB Network: if I navigate directly to the channel it may give me a black screen, but if I go to it using channel up/down it displays normally. I haven't seen either behavior from other channels.
