I noticed something interesting tonight while watching tivo. I was watching ESPN and the emergency broadcast system came on. The text of the warning came up on the screen and the audio was from the national weather service person reading the warning with some added information. What I noticed is that you can't change from this to anything else until the message is done. The guide, channel and tivo button do nothing during this time. Has anybody else had this happen? Does the warning automatically come up if you are watching something you had already tivoed and not live TV?
