Does anyone know what is the optimal exporting workflow to be able to but the file into DVD Studio? Thanks!

Export using compressor from the FCP timeline encoding both an M2V and AC3 file at the same time. That's the way I do it at least.

that makes the video and audio separate right? i remember doing that and on one i just got audio and the other i just got video! hahaha and i had no idea what to do from there? I'm a newbie at anything besides final cut in the suite.

I was surprised at the beginning too.
But it's all good. You import both into DVD SP and pair it into a track.
One thing you have to watch, which I had a little problem with at the beginning (didn't read any tutorial), is that you watch how you add the pairs to the same track. I stopped doing it. Many times the audio was different length than video by few frames. Then when I added next pair, it was out of sync by that amount of frames. Maybe it has something to do with that I'm not marking my in and out points when I export from FCP, I just export the whole timeline.
Anyway, now I always use each pair as the next track.
I hope it makes sense.
