Audio is not same length as video - please help!

I'v been visiting the forum a long time and in all that time I havent yet posted any of my edits - mainly because I'v never followed any of them upto completion. The thing is, I work a little too slow. I started work on Superman II and then I got a HD TV and figured I may as well start again but with an HD source. Until then, I thought I'd revisit TPM to see if I can make it work for myself.

But one problem that has always occured for me is that the Audio and the Video have never been the same length. See here

Everything looks fine when it's zoomed out...

But now you see that despite the beginning of it being in line with each other, for some reason the audio is longer than the video.

On the last pic, ignore the fact that the timeline is different - it didnt save the 3rd example so I had to re-do it again.

But can anyone help me? I thought that perhaps it was a result of exporting a NTSC movie and then starting up a project in PAL. But this is not the case at all. The movie is Region 1 and thus NTSC and so is the video. The audio is 48hz so no sure if this could be causing it.

To export the footage im using DVD Decryptor and then fixing the time code errors in Womble.

I'v done an edit of the Pod Race and the bits leading upto it and I must say Im very pleased with the work. I feel it has an energy that it didnt before but I dont want to go the whole hog due to this error. Can anyone help?

Yep, the sound is only longer by one Frame...and the project is set to NTSC (29.97) although the Display format is 30fps - Drop Frame Time Code. Although if I click on this I only get the following other options:

30fps Non Drop Frame Time Code

Feet + Frames 16mm

Feet + Frames 35mm

Frames

When I extract the footage I use DVD Decryptor and demux the audio and video. Is there now a different way of doing it that works?

Sorry, it's actually 3 frames that the video is longer than the audio.

Those are the settings within Premiere. I just tried a 23.976 frame rate in a new project and im getting the same problem.

Guys, am I actually doing this right? This is the procedure im using:

1) Open DVD Decrypter and extracting the audio and video. When I do this I am De-Muxing both.

2) Fix the Time Code + PTS errors within Womble.

3) Transfer into Premiere and start editing.

I used to merge the two into an avi using HuffyUV codec but now dont do this but im wondering if perhaps I should? When you guys do re-edits what are the procedures you do?

Right! I think I'v sussed it out...the audio is only out of synch when I use the extra 6 channel sound. :( But I was hoping to have Surround Sound in my project :(

Any ideas guys? 2 Channel is fine.

Now I'v gone back to a previous chapter with 5.1 and the problem isnt there now! I think im going to do what you suggest mate and just work in 5.1 and if I get an error to try and work around it with edits and suchlike.
