For sure MoveiClip can be imported into the TextField inline of your texts...
But there's an easier way also possible from now on, not only the easier way but also more efficient and powerful.

The site produced a class named "TextArea" which is an extension to the original "TextField" class that ends to the shortcomings of TextField.
TextArea not only allows to have MovieClips and SWF files in line of your texts but also allows and created the most efficient ways to communicate with your SWF file live at any time, it allows to have different HTML tags rather than just having the tag to import images, you can have video player, talking avatar, flash buttons and anything else with their own tags to even set their settings dynamically right from your dynamic content.
It has lots of more features and doesn't specifically limited to this issue. Check out doitflash for more information. the site provides the platform and downloading it is also free of charge :)
