Surround Sound CD Player and Commercial CD's?

Recently acquired a 2004 V70 with premium sound system (HU-803) featuring pro logic surround sound. However, 2 new surround sound CD¹s at Best Buy wouldn¹t play, and another that I know works perfectly on an Acura TL surround system also won¹t play. Service manager says he has had other customers complain about the same thing; that it¹s a VOLVO ³software² thing. Apparently it is not compatible with certain commercial products. Is this true? The CD that I know is playable is a 5.1 music disc that requires a DTS-capable playback system. I don't recall what the Best Buy discs were other than surround sound. What kind of discs will play other than ordinary CD¹s? Rob---
