Dear Jay,

If you can see that the pipes are not swapping at the same time it's not
the genlocking that is wrong but the synchronous swapping. The
genlocking synchronizes the frames (between screen refreshes) in the
different pipes and normally you run at refresh rates between 66 to 120
frames per second. I think what you see the pipes not swapping from
front to back buffer at the same time.

If someone knows how to force performer into swapping pipes at the same
time (probable by using the swap ready kables) please tell me !!

Wilfred
