How do I author a playable DVD from an MKV file containing MPEG2 video, audio, subtitle and chapter streams? I'm using MakeMKV to back up my DVD library to MKV files without re-encoding the video or audio streams (since space is cheap, and quality is top priority.)

I'd like to know if there's a tool available (Linux or Windows), or a procedure using a collection of tools, that would allow me to rebuild the folder structure for, or even burn directly, a DVD player-playable DVD from these MKV files. I don't want to have to re-encode the video or audio streams.

Many thanks in advance!
DVD requires more than just the video and audio data streams.  It also needs all the menu and table of contents data to instruct the player on how to play the stream.  As long as the stream is in an appropriate format, there is no reason that a DVD authoring package should have to re-encode the video.  It just needs to take in the stream and rebuild the menu and table of contents information that is needed to tell the DVD player how to play it.
