Here's the scenario... I'm watching live TV, then I go to Replay Guide and select a previously recorded program to view. When I've finished watching it and go through the "delete the program" operation, there seems to be no way to go back to the live buffer WITH THE PREVIOUS BUFFER INTACT (ie, you can only get back to viewing the previously tuned channel by going through the Channel Guide which clears the Live Buffer). Am I understanding this limitation correctly? If so, I sure wish they would fix it... Tivo allows me to still see the previous 30 minutes after viewing a recorded program, and it's really come in handy.
