How about a "Closed Caption on Mute" option. When enabled.. Captioning would appear whenever the "Mute" button was "ON". I've had a couple of TVs with this feature. It is handy when the phone rings and you still want to keep track of the live program. Yes, I know it is a DVR, and Yes I know that the whole purpose is to rewind and play again. However, there are times when this would be handy. Should not be a biggie to program.
