My previous surround sound system was a Panasonic 5.1 - and compared to this it was awful. The menus, sound, setup, all great on this. There are a couple of problems I've experienced.
First of all I was made to believe that the apps had lovefilm and iplayer. iPlayer is nowhere to be seen and lovefilm is 'coming soon'. I've updated the firmware, reset the apps, etc.. but still no iPlayer. Which leads me to believe there's some newer model with iPlayer - and the apps are generation specific. Since there's only about 12 apps total in the samsung app store. Dissapointing, but as I'm getting a new samsung TV in a couple of weeks I'm not too upset- hopefully it will work on that.
Secondly the wirelessness of the back speakers are a tad confusing. If you want the speakers layed out like I wanted them, with 2 up front, 2 on the sides and 2 behind, then forget it. The wireless speakers are the side ones - and have to be connected to a wireless box which is about the size of a house brick. This makes no sense at all, since to make this work I'd have to put the wireless box in the middle of the room, under the sofa - and have the power cable trailing over the room.
I think they want you to have it using 'Dolby Prologic IIz' mode - which I have come to understand means that you have 2 speakers at the front, then another 2 at the front - but higher up - then the 2 wireless ones at the back/side. Then the wireless system makes a bit more sense. I found it all a bit confusing until I realised this - so I hope that will help someone out.
