3D auto-detection help
Tried my first 3D blu ray (Dredd) and my tv wouldn't auto-detect the 3D signal. Setup is Sony BDP-S490 to Yamaha RX-A1010 to Panasonic 50GT50. 1.3 HDMI cables. I plugged directly into tv and it worked then plugged through amp and it worked. Turned everything off and tried again and it didn't work. But then an hour later it worked. Now it doesn't work! Is this a common problem - not a good start to my 3D experience.
