Hi ClubNeon,

I think that what you are refering here to is Sony's format for commercial movie theatre called SDDS - http://sdds.com/.

Dolby's 7.1: According to an article in Widescreen Review . . . An interesting point is that even the rear speakers should be located on the side walls not the rear wall . . .

" The optimum 7.1-channel surround format for home theatres is to position the "two added" channel loudspeakers to the sides, not to the back of the listening area."

Yeah, it was the SDDS encoding which had the additional front speakers. Haven't see too many films with SDDS bumpers these days. Also Sony never pushed for it to be an encoding format on any home media.

Interesting about Dolby's recommendation. I have a feeling they did this to appease theater owners. There is already an array of speakers along the walls. Each with their own amps. That means all they need is a new processor to send a different signal to the last pair of surround speakers. So they only have to buy gear from Dolby, and no one else, for this upgrade.
