Need some help with a synch problem

Hi, I hope this is the right forum for my problem.

I'm preparing a movie for publication on DVD. Mainly I generated
subtitles, but I also took a look at the video and audio source.

At the beginning of the movie there is a company logo (Toei)
for 13 seconds showing two waves of water rolling to the coast.
This intro clip had a rather bad video quality, while the rest
of the movie looks excellent. I got a great assistance in a forum
to restore the intro clip. Among other things there were
duplicate frames (10 or so), which are removed now.

However video and audio of the intro are totally out of synch
now. Since the video is done now, I'd rather like to shift/stretch
the audio appropriate. No problem to do so - if only I knew, how
much I had to shift/stretch/insert/...

Moreover, video and audio seem to be out of synch even in the
original source, so I can not compare to the original. I have no
idea of the history of the intro clip - maybe it was converted
from NTSC to PAL, but that's just a wild guess.

In the audio editor I can see the two breaking waves very clearly.
They start, come to a maximum of volume very quickly and fade out.
The only thing I really miss to find out is, at which 2 frames
I should place the volume maxima. (If I try it again and again
at the end I loose the feeling, what's right or wrong).

Could someone with a good feeling for synch take a look at the
intro clip and give me some advice where to put the wave maxima,

The clip is at http://www.megaupload.com/?d=UCW22JRS (9MB).
