To burn a DVD that you want to play on commercial DVD players, you have to use the mpeg2 codec. Even if you export your video in another codec, such as h.264, the authoring program you use (Encore, DVD Studio, any of them) will re-compress your footage to mpeg2 because that is the only codec that DVD players recognize.
So to answer your question, always export your footage initially to mpeg2 DVD other wise you will just be compressing your footage twice and possibly compromising the visual quality of your video. By the way, the mpeg2 extension most often looks like .m2v, and only holds the video. The audio should automatically come out separately as a wav or AC3 file depending on the program you use to export it.
