I have a Sony VGX-TP3Z/B - Home entertainment centre (link below) that I have connected to my B&O 7-40. How can I listen to my music or video / dvd on other linked B&O TVs (Beo 8, an old Avant & a mx4000)? http://vaio.sony.co.uk/view/ShowProduct.action?product=VGX-TP3Z%2FB&site=voe_en_GB_cons&pageType=Overview&category=VD+TP
