Problem with Beowulf

[bigdaddyhorse]

So I just returned one copy of this and am still having the same issue.
I get nothing but bass for sound through my receiver. Everything is hooked up right, I watch at least a movie a day and haven't had any other issues (except the Dredd fubar discs I expected), but no matter what I change the input settings to on the player, I only get bass on the US audio (the other 2 tracks work fine). Even weirder, the sound comes through my crappy TV speakers fine. WTF is happening? I want to watch this but 2-channel TV speakers are a waste of my hearing, why won't it sound right?
I have a Sony BD-S370 player and a Denon AVR-589 receiver if that maters. Thanks in advance for any potential help. Gonna try and hook up the Magnovox player to see if that helps, but I doubt it will.

WTF squared? It's fine through the Magnavox 530. Irritating at best (running up and down stairs, unhooking and re-hooking), but at least I can hook that up to the HD set and receiver. Why no good on the Sony 370 though, which is a far faster (load times about half) and better player overall?
