Only some MPEG-2 codecs are still under their temporary, granted
monopoly period, and others are licensed to the public Several of the
common ones are not, including those that ship under Debian, Fedora
and other distros that are very "anal" on this.
Furthermore, if you did not license under the MPEG-LA and you are
not subject to royalties as long as you are utilizing MPEG-2 features
that are not currently under the granted period of monopoly of their
patent or otherwise licensed to the public by their holders.
Remember, MPEG-2 has a crapload of features that have nothing to
do with DVD-Video format and playback and are not required.

pool is managed and administered by MPEG Licensing Authority, a private
organization. Other patents are licensed by Audio MPEG, Inc. The
development of the standard itself took less time than the patent

technology is subject to royalties.
* Encoders are subject to a royalty of $2.50 per unit.
* Decoders are subject to a royalty of $2.50 per unit.
* Royalty-based sales of encoders and decoders are subject to
different rules and $2.50 per unit.
* Also, any packaged medium (DVDs/Data Streams) is subject to licence
fees according to length of recording/broadcast.
In the case of free software such as VLC media player (which uses the
ffmpeg library) and in which the software is not sold, the end-user bears
This could be one reason why the most complete DVD generating software
is on MACs and Windows and is not freeware.
How many of us have paid our mpeg royalty? :-)
