Flash in DVDs

Hi I’m trying to make a DVD menu that can access different flash SWFs and play them on a set-top box. I’ve done some searching and saw some video editing tools (such as Vegas 5) have SWF import options. Is it possible to load a SWF that relies on external sources itself to run (i.e. txt files, external swfs) and play on a normal DVD? If anyone has experience in doing an operation like this and knows the limitations of Flash within DVDs/CDs running on a set-top box I would love to know the details. Thanks!
