Thanks DigMod, it was more to get tips on how they removed or reduced the score but I might take you up on that.

Having spoken to Possessed his edit is not presented in 5.1 with discrete channels. It is surrounded encoded, but it’s matrixed 2.0 surround like pro logic or dolby surround. So while it will upmix very well for a surround experience there will be a little bit of bleeding between the channels. Which wouldn’t matter for viewing but it might make editing a bit difficult. I’ll know more once I’ve processed the .iso file.
