Yeah, I guess you're right about the recording levels. I suppose with newly pressed DVD's such as this one a person tends to expect a
higher fidelity (volume, etc) on these discs from the existing technology

.
Some threads in related forums have also suggested using
presence speakers to expand the output of the center channel (dialog) but I'm skeptical about doing this; I've not seen anyone categorically state that this is the cat's meow for extending the dialog output.
Thanks for your reply.
