Hey is there any way of having a unity player, video, or game as a interactive media background. Like flash for an example, using unity to set up buttons and triggers to play videos, a 3d background, a game (per sue), and/or links. And exporting all of that to as web site, or to a DVD.
Everything is possible :) However the scope of your question is a little broad. It sounds like your best deployment scenario would be the Unity web player, and scripting interaction between other hosted objects on the page(s) and the player:
there are limitations but it's possible. like director and flash you can not play multiple file formats and render HTML content. just jpeg and gif images and ogg audio and quick time video. for these cased director is a better product but it's 3d capabilities are rather limited.
if you want to mix unity content with HTML/Flash/Silverlight content then you can use browser's javascript to do that easily.
