right surround louder than left or placebo?

[STARSCREAM]

Ok to start off, I got the new Onkyo ht-s9300thx system have been putting it through various tests with demo material. Everything sounded great and balanced. Then the other day I put in the Star Wars A New Hope dvd (special edition 2004 version) and noticed most music was blaring from the right surround. I googled and looked up that the music on this release had the surrounds reversed from what they should be for the entire soundtrack. When playing the French 2.0 track, which by the way doesn't have the reversed surrounds problem, the balance is much better and now lots of it is blaring from the left surround which makes me think the problem all along is the reversed track making me think the right surround was louder.

Anyway, every since that night I seem to think still on everything that the right surround seems to be playing louder, like higher frequencies and stuff too. When the music is or something is playing in both surrounds at the same time it always seems the right surround is louder. I boosted the db level of the left surround by 2-3 db to see if that would match it and while it might have helped it just doesn't seem to hit the same high frequencies as the right surround. Does this sound plausible to anyone???

I have run audyssey on my reciever a few times now for setup. Also, I have swapped the left surround with the right surround many times to test. It might just be in my head and placebo effect but it seems when I swap the speakers instead of the right surround being louder than the left it is now louder in the left than the right which always makes me think the problem is the actual speaker that somehow it's not playing all the frequencies or something. I don't know, it's driving me crazy though and it might just all be in my head!! I'm OCD so who knows. I'm one who always thinks something is wrong with my stuff and I need everything perfect. Maybe it's also my seating postion, maybe if I move one way or the other it will balance the surrounds out?

Sorry for the long rant but I've only got a few more days in my return window so if something was wrong I'd need to return it in the next few days. Bigger thing is I don't wanna exchange if nothing is wrong because I'd have to return everything so all 7 speakers, sub, and receiver and the box weighed about 140 pounds and then I'd have to get a new one and go through all that unboxing again, ugh.

Right now my daughter is watching the blu-ray of the second Tinkerbell movie and I'm sitting over alittle more left than I usually do and the sound is balanced sounding out of the surrounds, sounds good. Maybe on the others it's actually just the mixes of the audio tracks. The two I tested most were dvd's of Star Wars: A New Hope and Return of the Jedi. Those were mainly the ones It seemed the right surround was louder. I tested Avatar blu-ray, first Transformers blu-ray and they seemed fine.
