6 Frame Audio Sync Issue with FCP 6.0.5

I've had something crop up on my system for the last 4 projects I have worked on. Clips are capturing fine into Final Cut, but when I play them back, they are exactly 6 frames off in sync. This happens to all clips that I work with. If I move the audio tracks 6 frames to the right, things sync back up, but I don't understand why this is happening. I've checked my capture settings and the audio/video sync box is checked in the user settings. Anyone have an idea what is making FCP lose sync on my clips?

PowerBook G4 1.33 Ghz, Mac OS X (10.4.9), 2 Gb of RAM

Are they out of sync when viewed in QTPlayer?

How are you capturing and what format?

How are you monitoring...computer screen or external broadcast display.

What is your 'offset' under Main Menu/Final Cut Pro/System Settings/Playback Control tab - frame offset...you might try adjusting that.

They are not out of synce in QTPlayer. I am capturing with both a Sony DSR-11 Mini-DV deck connected via Firewire 400, and I am also using Screenium, a screen-capture utility to grab some video from the computer screen of a Web browser. I'm having sync issues all the way around. I tried changing the offset in the Playback Control tab from 4 to 0, but nothing so far has helped.

If they're not out of sync in QT, then you might try playing with more offsets in FCP.

'4' is a pretty standard offset for DV. You say you're seeing 6 frames out of sync, so try changing that to 10..see if that helps.

I see up to 28-30 frame offsets when working with DVCProHD, while DV is 4 and on occasion I'll see 15 when using DVCPro50.
