For converting .mkv to DVD format I use ConvertXtoDVD, which is a sweet little program for $50.

And not only that...you can also drag and drop multiple video formats into this program and click one button to burn them all to a single- or dual-layer DVD. It will convert (multiple formats at once), compress (if necessary to fit the disc type you choose), create menu with video "thumbnails" (one for each video file), and burn - all with that one click.

The default menu color and style is fine with me, but you have myriad customization choices for all of this as well.
