I've worked with companies designing such things. However you left out critical details for me to tell you specific steps. The good news is that the companies that made such supplied their tech support with the answer on how to do this.

But since no one tells the make and model I'm going to only respond with the GENERIC answer. Here it is.

Step 1. Move the video to your PC. It does NOT matter what compression at this step since your spec of "DVD" forces what happens next.

Step 2. Go get DVDSANTA (google.com). The demo is free and you can make a DVD from your file in step 1.

We are done. And we didn't have to deal with compression since it's going to DVD and that is a standard.
