/**
* The basics of DVD encoding.
* <p>
* This example is very unsophisticated, there is a minimal progress indicator, but it does show
* working DVD encoding.
* <p>
* Note that you must use a DVD that has no encryption, or you must have the appropriate DVD
* decoding libraries installed.
* <p>
* Specify three things on the command-line:
* <pre>
* [dvd-device] [output-file] [preset]
* </pre>
* For example:
* <pre>
* simpledvd:///dev/dvd /home/rip.webm WEBM_LOW
* </pre>
* It is recommended to try the WEBM_LOW preset first.
* <p>
* Encoding a full DVD is going to be slow.
* <p>
* In principle, a start-time and end-time could also be set via media options - e.g. to trim
* out unnecessary intro or trailing credits from the movie.
