I have a theater set up with bluray, dvr and xbox360 all routed through a receiver via hdmi. Signal then routes through a 3dxl to a gt720 projector. Bluray 2d, 3d and dvr work great but the projector will not find the xbox. If I bypass the 3dxl the projector does find the xbox. 3dxl has the latest firmware so I'm at a loss to why I can not get the xbox through the 3dxl. Any ideas would be helpful.
