Ik have the Event Horizon european blu-ray. On this disc you only have a Dolby True HD english soundtrack, the standard DD tracks are in german, french, etc. The problem is that the core 640 Kbps track of the TrueHD track plays in Stereo on my Yamaha RX-V440RDS, not 5.1 like it does with other TrueHD titles I have. And because there is no standard DD track on the disc I'm stuck with the stereo sound. So I suspect they made a mastering error creating the core of this TrueHD track. Does anyone else have this problem?
