I have just installed a Viera 50 inch plasma. Great picture and excellent toy. However I do have a problem. I was watching 24 the other night with 'big' sound. My wife and I noticed a buzzing and sound breakthrough from what I suspect is the Sky connection. I was feeding the Viera with a DVD signal from a Pioneer DVD545. My HiFi was providing the sound; Cyrus stero amplifier connected via the audio out phono sockets on the Viera. I had buzzing on both the Viera and Mission speakers. I have reduced most of the buzzing through use of the Viera's supplied ferrite cores, one on each scart lead, and one on L & R phono leads. I think I can now tollerate the buzzing level. The problem I am left with is the sound breakthrough from what I assume is the Sky connection. My connection configuration is: Sky - AV1, Phillips DVDR looped through Sharp VCR -AV2, Pioneer DVD545 - AV4. (also a loop from Sky to DVDR.) Any suggestions on curing the sound breakthrough? PS I don't get any of this buzzing or sound breakthrough on my Toshiba projector/Marantz AV receiver upstairs.
