thanks for the response.
No, I’ve only got the camera attached via firewire although to be fair I don’t need this attached when editing. I’ve killed all processes other than windows and premiere so I can be sure its not a virus scan or anything like that kicking in. I hadn’t thought about disconnecting all the usb devices though, might this help?
What I can’t understand is why I can scrub through the timeline just fine and see the video and audio as it should be but then as soon as i press play it craps kittens.
