Nobody here has apparently used the 3DTV glasses then. Eniweys, I got 4 of these, and happy to note that I like them more than my NVidia glasses. It can handle bounced IR signals off the wall where my projected movie is, even if the emitter is on top of the CPU at the rear wall, almost 6 meters away, for a total distance of maybe 9-10 meters. The NVidias, flickers all the time with the bounced IR signal. I need to get a long USB active extender cable to hopefully get the NVidias to work for my setup.
