Default Re: Video Sync Offset in PT11 not that useful

I finally got around to checking our PT 12 systems with the Syncheck II. We use the Blackmagic Intensity Pro cards, and the result is very stable. With our previous setup, the Canopus with PT 9, it was all over the place, sometimes locking almost a frame out, and constantly drifting. Now it is stable within a ms or 2 with no genlock. Adjusting milliseconds, it doesn't change until you go above or below 20 ms. Anything between -20 and +20 keeps it at zero. At a setting of +21 ms, Syncheck reads +32 ms (about 1 video frame). At a setting of -21 ms, Syncheck reads -49 ms (a little over 1 film frame). We have delay for our projector built into our B-chain (crossovers), so the 1 frame resolution isn't a problem for us. When I first saw the ms setting, I thought "This is awesome!" Too bad it doesn't work.
