I have an HW-J7500R surround bar, a JS9000 TV and a pair of R1 speakers being used for rear left and right surround.
I seem to get constatnt drop outs of the Multichannel system out to just TV sound and have to set the system up from scratch via my iphone. This will happen on average twice during a 2 hour movie. The Wifi is BT's most advanced whole home system but I had the same issues with my older Home Hub 5 and my previous Sky hub.
Any ideas what is kicking the wifi connection out?
Also, on another note, have Samsung given up with the Mac OS X multiroom app, I loved it but it now crashes on boot-up every time and I can't find any updates/bug fixes.
Samsung need to take a long look at the Sonos system and aim for that level of features, stability and connectivity to make their surround systems competitive.
