There are 36 pages to this topic, so excuse me if I'm asking a question that was already addressed.
I have a Pioneer DV-610AV, and I am also running a quad setup (4 channel) with no center and no subwoofer.
My problem is that DVD-A discs are missing vocals (The Doors Perception box set, for insance). I'm not sure if SACD and DTS are experiencing similar problems, because I only have one disc of each (Pink Floyd DSOTM SACD, and Queen: A Night at the Races DTS), and neither of those seem to have any vocal drop-out.
So my question is: Was there ever a solution for this? I'll go back to my Samsung HD-841 for SACD and DVD-A, but it can't play DTS. Plus the rest of my gear is Pioneer, so I was hoping the DV-610AV would work for me. If there's a way to fix this (some obscure setting or a bios update), please let me know.
