This card is causing some strange behavior??? When I first installed it - it made my preview on external monitor glitchy as hell. Then I switched the firewire cable from my Pyro card to the Audigy 2 card the preview is solid as a rock(more so than ever) but now the sync drifts after every transition - even if I pre render? Sync offset in the prefences will not correct it as the sync is fine untill a transition is incountered.
