and where would one put the other channels??
If one HAD SDDS audio to play with one would HAVE to probably spend a large amount of cash for a system that would do 8 channels of surround like a theater does. Then, the money it would cost just to capture SDDS would be more than said surround system.
The one other thing to remember .... SDDS was the least reliable due to it's placement on the film stock.
