losing voices during some movies?

[VRDUB]

Have you tried turning up the volume for the "center channel only" in the set up menu? I too had this problem and I turned up the center about 1.5dB louder than the rest of the speakers, and to me this was a big improvment.

Have you set your speakers' distance/delay and then calibrated their levels with internal pink noise?

Have you checked you connections, both speaker and audio?

Is your CC-470 positioned properly?

I have a CC-470v3 atop my Mitsu 55411 and it performs flawlessly.
