Apologies for going slightly off-topic (I have a BV10 so I'm excluded from the poll for the moment), but when I was enquiring about a BV11 or Avant, a dealer told me that setting up different listening positions would be effective only with a 3-speaker setup (2 external, front only), and that it would not work properly with 4 external speakers(2 front + 2 surround)... Is that accurate information?
With apologies to your dealer: This is not only inaccurate - it's incorrect.
Consider, for example, an Avant with 4 external loudspeakers - Lf/Rf & Ls/Rs in the "normal" viewing position.
You could, as an example, sit on the TV and face the "surround" loudspeakers and create a Speaker Group that makes them Left Front and Right Front.
If all of the external loudspeakers are matched (i.e. the same model) then you could also use the room "sideways" by making a Speaker Group that uses the Lf loudspeaker to play the Right Front channel and the Ls loudspeaker to play the Left Front channel. Then you sit between the (normally) Rf & Rs loudspeakers (which are turned off in this Speaker Group) and face the left side of the room.
