sounds slightly out of sync sound on dvd's

When I burn dvd's of projects the sound seems to be slightly out of sync, not on all cut's but on some. What's the solution here?
I work on a 2.5gigs G5.
Would a video card help? And if that's so, how large a card I should get?

video card has nothing to do with this.

how are you burning the discs?

<<<not on all cut's but on some.>>>

And if you listen very carefully to the timeline everything's OK?

Did you use MP3 sound tracks anywhere in the production?

Thanks for getting back to me.

I export out of final cut to Quicktime movie, then iDVD
Or for larger projects, I use compressor and use DVD Studio Pro.

The problems appear to happen more so in iDVD though.

For short projects iDVD is so easy to use, but perhaps not the best way to go then?

When I say out of sync it's usually no more than 3 to 6 frames...

There's nothing wrong with iDVD.

What about the two questions I asked? Any MP3s? Is the timeline perfect?

Koz

Sometimes that happens to me if I use analog material, capture through a dv converter, in my timeline. It could also be that your viewing the movie on a cheap DVD player, that affects the sync between video and audio as well.

Thanks Kevin, I did not share that I do deal with a lot of analog material, both VHS and DVD that I'm taking in through a DSR-11. How do you deal with it?
Just move the sound a touch in the timeline? It's off sooo little, it can be a bit difficult to hear at times...

I guess Koz, that perhaps it's not completely perfect in the time line.
What's the MP3 issue? Not recommended? I do use them once in a while...

You should stop doing that. FCP will appear to be accepting your MP3 files just fine, but then later you start having sound problems and can't figure out where the trouble is coming from.

That's why I asked you about this particular show. The worst thing that FCP does is not make a fuss right up front and save everybody a lot of headaches.

Open in QuickTime or iTunes, convert to 48 KHz, 16-bit AIFF and *then* use the tracks in Final Cut.

You can run into sound sync issues if your [View, External Video, All Frames or None] is set wrong. If you have All Frames set, then the external monitor and sound are in sync. If it's set to None, then the computer monitor and local speakers will be in sync. You can't cross them.

If your Timeline isn't perfect, then yes, you need to unlock and slide the tracks a little to put everything back in sync. That's more editing than I know how to do, so you just drifted out of my world.

A few things to consider.
1) Slightly out of sync would be a frame or two at most. 3-6 frames out is a lot and easily noticable.
2) Are you doing an audio mix down prior to export from FCP?
3) How are you monitoring audio and video out of FCP?
