source ntsc. so somewhere in the region of 29.97Hz ( though not necessarily accurate )
is this a pro camera or an cheap camera setup?
which LED product is/was it?
dmx or dvi?
suggest as a potential first step you try setting frame rate to screen div 2 and see whether it gets better or worse

its related to the problem of how to play back the 23.98 movie we had before-
its the same kindof deal-
NTSC video camera signals dont fit neatly into dvi/vga/LED controller refresh rates.
