I'm not sure I'm expressing my question correctly. Let me try again.
I have a 6.1 speaker system, so I could either use ES/EX mode or Dolby PLIIx Music mode in the Extended Surround settings. I want to decide which setting to use. How can I find out what the actual differences are between the two settings?
I don't really need to know the difference between ES and EX (because its the same setting in the receiver), or the difference between PLIIx Movie and PLIIx Music (because I have 6.1 speakers not 7.1 so I can't use PLIIx Movie anyways)
No. ES is applied to any DTS input and EX applied to DD. (These settings are only relevant to 5.1 inputs)
Does ES/EX Extended Surround mode create a rear surround channel from any
5.1 DTS/DD soundtrack or only ones that contain the ES/EX digital flag?
