MX2K4: Images and Thin Lines Flickering When in Motion

I have a small, albeit rather annoying, problem with images (particularly those that have vertical lines or hard edges on colour fields) and thin vertical vector lines flickering in and out when they are in horizontal motion. Generally this is the case when I am moving a graphic with ActionScript in variable speeds.

My first guess was this had to do with the frame rate not being high enough. Yet, even upwards of 30 FPS didn’t rectify the problem. My SWFs are being exported and displayed at high quality so I doubt this is a contributing factor.

You can see an example of this in the following document: http://www.forma3.com/stuff/flash/banner_services_test.html

When the main body content is slowing down once it reaches a new slide, you can see the lines to the right and left of the image flicker in and out. Does anyone have any idea how to solve this problem?

(Admittedly, this is a rather small problem, but you have absolutely no idea how often this gets brought up!)
