audio sync

Hello again

I was wondering how to go about synching audio to the timeline.

I've got one video track with two audio tracks and I want to add two more [audio] tracks, to match the existing sequence. Sometimes the new audio has the same TC (and sometimes it doesn't). The way I go about doing it now is if the TC matches I match frame from the timeline and get the exact TC then I find the audio source and find the same TC there and pop it into the timeline.

This is very timeconsuming. I've tried grouping and autosyncing but that seems to flatten the four audio tracks into two, which I don't want.

I'm sure there's an easier way.

Thanks!
