Jerry, I do have an external lipsync box available, but that means passing digital data through yet another box leading to potential issues with formats or jitter - something I'd rather avoid. It's a shame that the 861 is limited this way.

Radiance will ensure audio and video arrive at the same time, other than that it's not really the job of a video processor to handle addition lip sync delays? I'm not using the Radiance in my cinema yet as 48Hz output is not yet added.
