Any advice someone could offer would be appreciated. I just bought the jumbo (innovage) remote. I can get my cable box and tv to work okay, but it won't operate my Sony home theatre system. I have a seaarate tuner and dvd/vcr combo. The dvd/vcr and tuner are separate devices (actually, separate boxes). Any ideas? I've done the slow power button search but no luck. Is this device capable of "learning" or once again, have I just purcahsed a device that proves it's impossible to have one remote do everything? thank you
