I thought of this, but the Oppo manual said using HDMI is for when you have an A/V receive that doesn't support 3D. Since I have a Yamaha RX-V673 which does support 3D, I didn't think it would make a difference.
My HDTV is an LG 55LW6500 - is there any known issues with it receiving video directly from the BDP-103? I ask because I've seen some manufacturers/models having issues with jitter and stuff.
Also, this still doesn't fix the abhorrent sync issues. I've finally got it stablized with the latest Oppo firmware but not after a delay of 240ms.
