Question:

How should the seam from durock cement board to Drywall be taped?

I know cement board to cement board is taped with thinset and fibatape, but what about the seam at the sides that meet drywall? How should these be taped. What Materials should be used?

You can use the fiberglass tape. Just apply compound on the drywall half and thin set on the cement board side.

I use a self adhesive fiberglass tape over that seam, and apply 90 minute joint compound over the tape. I assume you are bringing your tile to, or just over that edge anyway. I also assume that that particular joint will be outside the shower curtain or glass, whichever you will be using.
