MTD ( Myth Transcoding Daemon )

MTD is part of the MythDVD plugin.

Transcoding ("ripping") a DVD requires you to run the Myth Transcoding Daemon (mtd). To ensure that mtd is configured correctly, you should first test it at the command line.

 $ mtd -n

The last line of text should show something like:

 mtd is listening on port 2342

This indicates that mtd is ready for use. Once you've successfully tested mtd in the foreground, type CTRL-C to stop mtd. You may then start it as a background (daemon) process.

 $ mtd -d


If you are converting a DVD at the "good" setting, you are converting from mpeg2, to mpeg4 (xvid) internally mtd uses the transcode program.
