Getting typical field combing effects when viewing and capturing with premier CS4 capture screen on LCD monitor. Using Sony TRV320 into firewire with a four pin to 6 pin firewire cable. Previously used Premier pro 1.5 on another computer with same camera and 4pin to 4pin cable with no problems. Could the firewire card or cable be causing such problems or might it be premier CS4? Have tried all clip and sequence settings but they don't seem to affect the capture settings.
