Video playback with Audio. Sync error?

[pip]

Thanks Nev, that stopped the clip from dropping frames every second or so as before. Runs much more smoothly.

The only thing it still does, which i don't understand the stats window, there is still a frame or so dropped when this pink bar (in image below) jumps from top image to bottom image. The bar then slowly decreases and then jumps back up every 10-15sec. On doing so the video glitches.

do you have any video inputs enabled? I have seen similar issues when several inputs where enabled... interestingly it seems to be a Snow Leopard thing...
