You have different possibilities. You should sell the DVD rights per country or area, that's the usual way. So you will get for North America (incl. Canada) approx 1200$ to 1500$, for Germany (incl. AT & CH) approx. 600$, Scandinavia about 300$ and GB about $400 and so on and on. But as mentioned before, depends to the quality and most important - if you have one scene only, nobody will care about you or have a look to the video.
