Thanks Mr.G for your help,
So, I decided to go ahead and do a simpler test to begin with in hopes of not having to tear apart my whole setup (which I was prepared to do to get this thing narrowed down). I stopped by blockbuster and picked up the "This Means War" Blu Ray again, I wanted the same Blu Ray that started me questioning the projector. I don't now why I didn't do this before, but I simply took the disk into the bedroom where the ps3 slim is connected via HDMI to a Vizio 47" LED television (1080p). Pushed play and Voila!...the same mess of a picture I saw projecting from the AR100U. Digital grainy noise from hell (definitely not film grain by the way). Slappin' mosquitoes.
I think this pretty much dials it down to either the ps3 blu ray players, or I just fell victim to a really really bad Blu Ray. I do however still see some digital noise when watching "True Blood" (not nearly to the extent of "This Means War") but I think I may be just looking for it. So, it's probably a mixture of both things as far as I can tell (not the best Blu Rays + PS3 Blu Ray Drive). If any of you happen to watch "This Means War" using your projector, please let me know how it looks to you.
Can any of you suggest an awesome Blu Ray to really knock my socks off with this projector. I want to feed it somethin' real. (I've read the Dark Night discs are pretty awesome, any other suggestions?)
