Please can anyone help - I have a Beovision 3 set as a video master, with video slaves being, an MX4002, Avant with VCR, and a Beovison 5. My audio master is an Overture tuner/tape. I would like to introduce a Beomedia connected to the Beovison 3, I appreciate that the best video connection would be to the Beovision 5 but it is not possible due to cable
