I just installed my new Samsung 1590c blu-ray player. So, I put in my old calibration disk. Is it normal that my surround speakers don't work. I have an old Onkyo 6.1 system. So far, it has been great. It doesn't have a HDMI interface, so I hooked it up with the DVD player via an optical cable. I think the Blu-ray discs work fine. But my old DVDs don't sound right. Is that normal? Thanks.
