When I attempt to play Avatar in 3D, I get an error message along the lines of "Your 3d player did not detect a 3d display. I have a Sony BDPBX59 blu-ray player connected through a Pioneer VSX-1021k receiver to an LG 60lm7200. 3D contect from DirectTV plays just fine when routed through the receiver. I have also directly connected the blu-ray player to the TV with the same error message. I have seen that this appears to be a fairly common problem for Avatar, but I haven't seen any particular solutions for sony players. Does anyone have any suggestions?
