With the 3D rigs we're using (3D camera = 3 frames, 3D processor = 8 frames, DIT = 1 frame, Video Asst. = 2 frames, 3D monitor = 4 frames) we've tested an 18 frame delay which we need to match on the Comteks, I've got 10 frames delay available on the 788T (using and have the Behringer Shark inline lined up for 10 frames (416.6 ms), to eye it all works, but I'd obviously prefer a DC powered unit ala AD-100 mentioned above,
