I have a Marantz SR7200, which is Dolby EX or DTS ES capable (Matrixed only). The issue is when the system is in Auto mode it will not detect EX or ES encoded material and the rear centre channel is dormant. In order to utilise the rear centre channel you have to force the system into 6.1ch surround mode. That’s fine except when in this mode the audio for the DVD software menus is muted as 6.1ch surround mode will only utilise 5.1 digital data (or better). i.e. if the DVD software menu sound set-up is in stereo or Dolby pro logic the 6.1ch surround mode will not decode this data. The other pain is if I put in a CD and listen to it on the DVD I have to constantly change the surround sound mode from 6.1ch surround to Auto or stereo so I can hear something. Similarly if I am in source direct the system will only operate in Auto mode therefore no sound from the rear centre even if it is EX or ES encoded. Am I doing something wrong or is this just how this receiver operates. If this is the case then the receiver isn’t detecting the EX or ES flags so is the 6.1ch surround mode decoding the rear centre data correctly? Any ideas?
