Gradient Color Display Problems

Hello all,

My problem deals with the gradient colors and how they won’t display correctly, or not at all. Here’s my website:
http://lynnandjanuel.com (a work in progress, of course)

When you click on the different buttons it brings you to different screens. Each of those screens has different gradients behind the text. Now, when I edit those gradients in flash, they are displayed smoothly, with so much gradient-goodness. But, when I publish and upload the .fla, the gradients seem choppy on the display, and some have bizarre lines running through them. I want them to be sharp and smooth, like in the edit mode.
Can this be corrected in the Publish settings? Or is it a problem of computer performance, too many layers or too much data in the .swf, or all of the above? I do have a lot of garbage in the .fla that I haven’t gotten around to deleting yet, but I’m not sure that would be the problem.

Any help is greatly appreciated.
