FX1 KonaLH Capture

Problem: We can view and capture SD Uncompressed directly from the
Sony FX1 component output, but all we get is a black screen with
occasional flicker of picture when trying to record 1080i direct to disk.
We have tried two different FX1s and two different sets of cables
with no luck. We succeeded in capturing direct to disk last fall
with this same setup. Have the updated KonaLH drivers broken
its ability to do this??

Dual 2.5G5, Xserve RAID, Kona LH, FCP 5.4 with latest Kona Drivers.

thanks
