24p Assets In DVD Studio Pro
You can use 24p material in tracks within DVD Studio Pro as well as in menus, as buttons and in drop zones. How DVD Studio Pro processes your 24p footage depend on how the material was encoded.

If you have already run your footage through compressor and have made 24p Mpeg 2 assets, then your footage will remain 24fps after you have built your project. If you import your footage as a 24p Quicktime asset, it will be encoded as either 30 fps or 25 fps when you build your project!
