Thank you for the information. You are correct. But the problem is we have always changed to another source and surround modes. I do it all the time, when listening to Cd's, or Pandora, or switching to the stadium sound for his football games. But this time... I turned on movie, notice it is on stadium, no biggie, turn it to wide screen mode to watch a movie and center is off, only two front speakers. On display it shows FR, FL, C, SW, SR, SL. I checked settings of that mode, all the speaker settings are exactly what they were prior. I turned up the Center volume settings just to see if it made a difference, nothing.
For example, Mono Movie mode works fine, sounds like Mono, yuck, but it works like it is programmed, the voices on a movie or show comes through center. Stadium, sounds like the stadium, all speakers at once, echo type like intended.
Stereo is FR and FL, Sub.
Widescreen is wrong. It is not in a surround type mode so to speak. It plays like it is in stereo mode.
