I am very interested in the LG SK10Y and may also get the SPK8-S rear speakers. I have a question regarding the "Surround sound" setting. If you are watching an HD broadcast TV show through your cable box, am I correct in assuming that Dolby Digital 5.1 is the typical audio format? In which case, the SK10Y would only output to the 5 speakers on the bar and the 2 upfiring and 2 rear would be silent. If the "surround sound" setting is enabled, what channels get sent to the upfiring and rear speakers? - Is it a smart algorithm that takes some of the surround channels and sends it to those speakers, or will I start hearing commentary from the center channel, etc in the rear speakers? Does the surround setting impact the 5 main speakers in any way? I just want to make sure that I can still enjoy the design of the 5.1 DD broadcast without the 7.1.2 speakers becoming only stereo all around when that surround setting is enabled.
Thanks so much for your help with understanding this.
