I have an occasional problem where, when watching a recorded programe, when I pause or fastforward/rewind, my subwoofer emitts a loud thump. I have my Tivo connected to a Receiver so the sound is played through my speakers and subwoofer.
Not 100% sure but seems to happen on TV3.
Usually I turn the sub off and then the next day turn it on again and its Ok
So I wonder if its something to do with the different audio processing TV3 uses versus TV1,2 and this is causing some sort of issue from time to time
Only only have a 2.1 configuration ie stereo +sub rather than surround sound.
