1080 settings and render help

We are trying to create a graphic for a set monitor for a shoot on Tuesday and are running into issues.
I had a simple :08 loopable 3d logo animation created in Maya, and handed to me as a quicktime with embedded key signal. The properties read as 1920 x 1080, codec is animation, at 30fps. When I drop it into FCP6 in order to build a 20 minute loop, it requires a render and it looks just awful. I really need to add a background to the animation, but with a background, without a background, whatever we do, it seems to look horrible. Any ideas exactly the steps we should be taking. We are also need then to get it onto DVD so we can pipe it into a monitor.

thanks in advance.
