I just watched I, Robot last night and had my first experience with DTS 5.1 surround and just like every girl de-virginized was pretty disappointed.
I used a WH2 for my rear speakers and wall mounted it to the sides 5 feet(1.5 m) both from the middle, 4 ft. high and about 2 ft. back. Was it the spkr. placement or was it the media. Noticed also that Dolby 5.1 was more discreet for surround effects than the DTS(weird).
Because of my frustration, I leveled the volume of my front L&R Wharfe 8.4 spkrs. to zero because I thought they were flooding my rears and true enough, I was able to sense some surround sound artifacts but was still left wanting.
I will hook the WH2 center tonight as a rear center and test my Seven Platinum ed (6.1 DTS ES) and hope that surround sound isn't overrated.
