Swf play speed and web page speed are Different

Question

Any idea why the swf's visual speed is different when viewed
as a swf or viewed from a browser page?
Some factoids: I have Flash 8.0, Action script 2.0. I have
published the swf (and related html) locally. 15 fps. The flash
contains animation, and an event audio.
When I author and adjust the timing of the audio and the
animation in my flash file it is synchronized. Further, when I
preview the animation it is synched. Also it is synched if I view
the swf from the hard drive.
However, if I invoke the swf's html file, either online or
locally, the visual significantly lags the audio.
It is not a matter of swf size as the swf is .4 meg. It is
not a matter of computer resources as the computer I have is the
latest model nicely equipped Dell.

Hi OT,
well, it's not so strange the difference in size.
As I wrote before, it's iWeb that create a new background image for every page.
In the page menu>layout you can choose the background image. My original background image file is just 152Kb.
But in that menu I setted the file as "Tinted image fill" and "Tile".
So iWeb "tints" my original file with a color and change it from jpg to png and then, istead of just "tiling" the image to fill the length of each page, it tiles the tinted image to fill the length of each page and then create a file of that length. So it's not a real tiling, and the background_1 file become different for every page.
In an other web site I just chose a background image and tiled it. Well the bg. file created by iWeb is smaller than the original one and it's really just tiled, so the file is the same for every page, even the length of pages is different.
The problem is the "tinted image fill" setting. As I wrote and as you tested, if you use a graphics editing software, you can create by yourself the "tinted image file" and then use it as background in iWeb without the "tinted image fill" and "tile" setting on, but just "image fill" and "tile" setting on.
The files you dowloaded from my site are not the original one. The original bg file is white with the paper pattern and it's 640X480 152Kb jpg file. You cannot find it on the site, it's just in my hard disk.
So I have to tint the original white paper pattern file with the green I like by a software and then save it as a small jpg file. In iWeb just set this new file as bg "image fill" and "tile".
