5.1 hook up

[daveb]

Hi
I have a system that works fine with 5 speakers + a sub woofer.
A Marantz AV5500 Surround Receiver a Marantz DVD Player.

I recently purchased a Panasonic Blu-Ray DMP-BD35 Player.

I disconnect the older DVD player and wired up the Blu-Player wire for wire, but now I am only getting stereo out of the two front speakers

Can't figure out whats wrong.

Any help would be appreciated.

Thanks
Dave
