How to display streaming video in registration form (custom profile field)

I am wondering how I can include a streaming video as part of my registration process. I am using JWplayer so this means <script> tags. There is no "Video" field type. However, in the past when I have needed some custom HTML in the registration process I have used a Text field that uses a lnaguage override, and placed the custom HTML in the language override text. This DOES NOT work for the <script> tag needed for the streaming video. Other ideas?
