HTML area integrated into flash?

Hi all, new to the site, and working on my first flash site… Good to be here! I’ve visited here more than once, but I have arrived at a question I cannot seem to find an answer to exactly. Oh, and I apologize for the crude drawing mock-up.

Basically, I have designed a site 1024x768 in flash. As of now it is a single flash document. I was originally going to build the entire site in flash as a single file, and essentially moved from page to page by advancing and skipping around on the timeline. I started to think this will create a large file, and low load times are a high priority. I have a banner area, and a navigation menu on the left, and a footer of sorts along the bottom and have left a large area for my future content for each page. On the initial load, I have the page coming together through a sort of “progressive fade”. And then from there, the user can navigate accordingly with every page staying the same, except for what appears in this “content area”.

So my question is I suppose, is there a way I can keep my flash site, but incorporate a small HTML content area which the flash buttons will change based on which is clicked? But all else will never change.

Let me follow that with, I have been playing around with frames but am not too familiar with them, and am not sure if I would have to “break up” my flash file into 3 files and then place those into 3 frames (banner, navigation on the left, and a footer) and then the 4th could be my frame for HTML. Is there any easy way to accomplish this? What are my options either way?

Below is a picture I mocked-up to describe what I am envisioning, and that whole thing at the moment is one big flash file with #4 as an open space. What I drew is kind of what I was thinking could happen if I used frames?

Hope this makes some sort of sense, thanks in advance! It will help me greatly… glad to be here!
