To understand the input format you have, please show us the console
output of
$ ffmpeg -i yourmkvfile.mkv

That depends on the resolution of original video. DVD is somewhat
restricted in what it supports. We'll see when we have the output of
the above command.

The real issue will be: If you have text-based subtitles, I believe
ffmpeg can't convert them. DVDs require bitmap subtitles (codec
"dvdsub"), ffmpeg doesn't provide such a conversion.

The rest can be handled fine. We'll show you.

P.S.: You can burn one of the text subtitle tracks into the video
      though:

      But that can't be what you want.
