Apologies for a second thread so soon but I'm now in problem solving mode(!) and I've one other problem that I've never resolved on the Pana EX77. The problem is this: When you are watching a recording, you can always here the audio (albeit at a low volume) that is being broadcast on whatever channel it is tuned to, even though you are watching a recording of something completely different! Once you hear it, it's very hard to ignore. Is there a setting on the EX77 somewhere that can cure this? Thanks, Graham.
