Hi, I have a SC-HT900, and have got Sky+ connected through the optical wire. From my understanding, only Sky Movies 1, 2, 3 and Disney have the 5.1 capabilities. This is all good and all, however, the 5.1 channels come out very quiet, and it's hard to hear dialogue from time to time. However, the normal channels are fine. Does anyone know how to solve this?\ Thank you.
