Directv just installed a new hr34 today and upon tuning to ESPN 3d we got no image only popping in and out of acquiring signal on the tv side of things. I have the signal passing through the hdmi of my sony strdh820 3d receiver, so it should pass through the 3d signal.... N3d works fine but my tv can't seem to see the espn3d signal.... I've hooked up hdmi from the hr34 to my samsung 550 59" plasma and it seems to work. I really don't want to feed the signal through optical cable, but I guess I will if I have to. Thanks in advance for any tips.
