SWFObject's Source path does not use the site's base path - only on the index page

I have flash components in several places on a website. I'm using the following code within the body of the page (using full html input formatting):

This code then generates the following html:

So, checkout the base path here - http:///files/ Obviously, this is not correct since the site is not inserting the actual domain name. If I "reset the theme" - or just switch from one theme to the other, the issue is fixed. However, it does revert back to this code periodically. I can't figure out why this is happening - this is only occurring on the home page, not on any other pages.
