With our new Denon AVR 589 it is currently in auto mode.
This basically means for TV1 and TV2 via freeview it decides to use Stereo. For TV3 it chooses Dolby Digital
For properly encoded DVDs it chooses Dolby DIgital or DTS
But the interesting one is Dolby Pro Logic II. This is automatically chosen for some things - such as for instance my wifes 2 channel stereo exercise DVD's etc.
I am wondering though is there any problem in forcing Dolby Pro Logic II mode for TV1 and TV2 which come through as stereo or should I leave the auto mode to do it's thing?
