Han,

How do you have your DVD players connected to the plasma?

I looked at the manual for the plasma and on page 34 it states: "Due to legal requirements, it is possible that with certain copy protected PCM audio qualities from a device connected to the HDMI input, the DIGITAL AUDIO OUTPUT signal is muted."

Not sure if this is the case but a possiblity.

Just another set of eyes...
