I know tivo instructions say, "pause a tuner" before switching tuners. Here's what I think is a problem. If I switch tuners without pausing and immediately return to the first tuner it has jumped ahead to live TV. I'm convinced the old software remained at the last playing spot (actually moved ahead the amount of time I was on second tuner). Is this the programed action or is this a change? If a change, it is a very bad one. A second problem is watching a program with a delay (say 15mins) and without warning the program ends and jumps to a record scheduled programs if both tuners are required to record the schedule. Again, I thought the old software would allow you to finish watching whatever time was left on the program before it reached the scheduled recording time. E.g. if you had 15 mins of delay playback left, you could watch that even thought 2 programs were being recorded. There was at least a question about the upcoming recording.
