Image Quality Changes During Transition

Hi Everyone,

I’m currently having a small issue with my flash movie. If you view

www.acceleratewebs.com/trevett/wordpress

You will see a swf on the homepage. I created the tweens using just flash, no as3 or anything. I’ve loaded outside jpgs into flash, then converted them to movieclips, and created a slideshow from them. As you may be able to see, as the first transition begins the left image that’s coming from the middle image (using a mask) for some reason loses it’s quality and glitches during the tween from the middle to it’s place on the left hand side. I’ve been looking for fixes with no result…any suggestions? It’s currently 40fps as well, as I tried that as a solution from 30fps.
