I thought with the lens in place Anamorphic C was the correct mode to watch scope content in, being that it would be presented “untouched”.

Basically just the reverse of the zoom method used to fill a 2.4:1 screen without an anamorphic lens. Does the zoom function not work the same when projecting through an anamorphic lens or is there some other issue I'm not aware of?
Using Anamorphic C with 16:9 content will remove the top and bottom 10% of the picture, which is what it does with 2.40:1 content. In the latter case, it's removing the black bars, in the former case, it's removing actual content.
Zooming is not relevant, because the Anamorphic mode is 'stretching' the central content part of the 2.40:1 content (that is the area inside the black bars), to virtually the full height of the chip. The lens, the 'vertical compression' type, then 'squeezes' it back down to its original aspect ratio. You are therefore using the full array of pixels on your chip (increasing both pixel density and light output), whereas before you were throwing away the pixels occupied by the black letterbox bars.
The Projector doesn't "know" if this is 16:9 or 2.40:1 content. It 'throws away' the area of that letterbox area, and it can't be reclaimed.
So with 16:9 content, you either use Anamorphic B, with the result being a 6% horizontal Squeeze, or Anamorphic C, which will maintain proper anamorphic ratio, at the cost of throwing away the top and bottom 10% of content.
Without an external video processor like the Lumagen Radiance Pro, there is no way of avoiding some type of compromise here. And even the Lumagen doesn't solve the problem with 3D content, such that a 6% squeeze is unavoidable no matter what you do, when used with the DCR lens.
To avoid these compromises, you have to remove the DCR from the lens path.
I will buy the RS2000 or its successor, if and only if, JVC provides the proper Anamorphic modes for all content. Removing the lens from the path is not an acceptable option for me, while it may be for others.
