I never used the 975 for 3D when I had it in my system as I don't have a 3D TV, never have. There are different types of 3D formatting. 3D TV's should support all of them. But, other devices only have to support at least one type. There's side by side and top/bottom formats, along with some others. There may be a conflict between your source device and the 975 in that they may support different formatting.
Or, I don't know what I'm talking about... shocked
