I feel pretty stupid replying to my own messages. I'll go ahead anyway.
I found the problem with the Slingbox Scart and Foxtel(Pace). The Scart connector supplied by SlingBox has internal wires that break out into RCA, Left, Right and Video. When the RCA connectors are connected to the SlingBox the voltage drawn unbalances the signal through the Scart, not effecting the BV7 but as a link connection it makes a difference. Simple fix was to use RCA outputs on the Pace box rather than the Scart.
I am sitting in a link room watching and listening to all sources connected to the BV7. I use the Beo4 to change sources and channels via a passive. If I can get Slingbox to assist on that front (Beo4 signals) all my B&O sources will be available on the internet anywhere in the world just the same as rooms in my house. Only the sources connected to the Slingbox are available via the internet now.
This could be the way of the future.
Beoaus.
