So, while you could put a 1080p .MP4 file (or most anything else) onto a DVD-Data disc, the DVD-Video format that most DVD players require is limited to 480p.
To create a playable video disc that uses high definition (such as 1080p), you would need to go with Blu Ray, which is a newer specification that's designed to handle this level of picture detail. This will require a Blu Ray writer, Blu Ray disc, and Blu Ray mastering software, and then you should be able to create a video disc with your full 1080p.
