Im having the exact same issue
In overall when playing a sequence in the timeline, using an external monitor, the first second is in sync, then the video starts to slow down a few frames and the audio gets heavily out of sync.
This is only happening in the external monitor. The video in the canvas or viewer is in sync.
I have already installed more than 20 Konas LHe and this is a first.
I already tried the following:
– Updating to Leopard
– Formating my Mac Pro
– Installing/Uninstalling Kona Drivers
– Running software update
– Using a different, cable, breakout box, monitor, DVCPRO Deck,
Thanks in advance for your support.
