Hey,

Just got an old sound system (Harman/Kardon AVR 130) that supports DTS and Pro Logic II. The problem I have found is that if I play media that have newer sound formats it sometimes does not use 5.1 but instead sends the L - R sounds to the back speakers aswell. Is there any media player that can handle the downgrading of the audio so that it will work with my older receiver? It usually works fine on Netflix with true 5.1
