OK, so, I've enabled the bezel overlay (Sega Naomi) and I'm trying to use a CRT shader beneath it. The one I'm trying to use is the Mega Bezel reflective shader (I can't remember the exact name) that centres the video image and adds a reflection around it. Problem is, it doesn't line up with the bezel. I'm wondering what (if any) shader you used when creating the bezels and what video scaling options you had (full/core/config etc).
Cheers.
