Motion interpolation problem with blu ray player

Today, I bought a new 60" TV and hooked it up to my Yamaha BD S677 blu ray player. When I played movies with it on my old TV it didn't have any motion interpolation and I already turned off the TruMotion setting on my new TV and it looks normal now. I have searched throughout the settings of my blu ray player and I can't find anything to turn off the motion interpolation. Why is my player just doing it now my my new TV even when I turned off the TruMotion?
