Its driving me mad....|(
I have just had a Tivo box installed and it is great. I use the optical out to connect to my Marantz NR1501 AV receiver/ Kef 2005 5.1 speakers. When I switch to the home menu page I get a loud click/pop from the speakers. This only happens when I am watching an HD channel. This did not happen with my previous V+ HD box or Sky Hd box.
