While this largely depends on the size of the Movie file you're burning, but in some cases, you can fit as many as 5 movies on a single DVD-R. However, it's important to note that when burning a DVD, all you're getting is the MKV file and not the additional bonus content, subtitles, or commentary tracks. It is possible to include these features when burning a DVD, but everything you add eats up space that could potentially be used for more movie files.
