DTS Master HD - No Center Channel Audio?? Common Problem?

[zachd73]

I am going nuts! Can't figure if this is a limitation of my system or if something is wrong.

I have a samsung 2500 BDP-2500 player and a Marantz AV Receiver.
I have both an optical cable and the multi-channel analong inputs connected as per the sticky thread on these forums (well, the thread details how to use multi channel outputs you know)..

I have tried a few blu-ray movies that have DTS Master HD audio. If I play through the optical it just shows and sounds as though front and center are playing with no surrounds. I think that is normal that the optical doesn't have bandwidth for the full DTS Master Audio track.

However, if I switch to Analong inputs - I can hear awesome sound coming from all channels except center. It's completely silent. On most movies there is no dialog at all, you can just hear everything but dialog from the other speakers.

I can't figure if this is normal or if something is wrong with my setup.

I tried switching the cables but that did not help.

Can anyone tell me if this is normal or not??!

Thanks
