After reading this thread now I'm curious. Were these titles ever remixed and released in 5.1 with actual information coming out of the center channel? Also, I was aware of the reissue of the Band on the Run to include the missing notes, but was that new mix in 5.1 vs 4.0? I've been around quad since it's invention too, but there has been so much repackaging of this material that I certainly can't keep track of how each version varies from the previous version. I didn't see your actual listings, but I looked at the link Jon provided for Mymusicfix. If the Steve Miller FLAE disc that guy is selling is 4.0 rather than 5.1 I would be confused from his listing. It states, "This is a DTS CD, which features DTS 5.1 Surround Sound technology and is playable on a DTS-capable 5.1 Surround Sound system." Nowhere does it actually say it's a 5.1 mix, but the way it's worded you could certainly easily come to that conclusion if you didn't know any better. So, I can see how people could get confused by the whole "5.1 Surround Sound technology" description. But asking for a discounted price because of it is idiotic. He's either satisfied or unsatisfied with the purchase. Your offer to return it and even refund the shipping seems very fair.
