I am getting crazy... Did a clean instal onto a new SD card and the result is same, surround mapped to the front.
kszaq, could you help us?
I managed it to work finaly. The LE I did nothing but turn of an on the AVR-s auto surround mode (so nothing changed in real) but it helped, every format is perfect 7.1
Sorry for annoying too much.
Anyway, kszaq, thanks for your great work:)
