I think you hit it, Matthew. The article states "... MPlayer/MEncoder (for
Linux) are usually able to overcome ARccOS". dvdrip uses mplayer/mencoder as
a backend, whereas it seems, the KDE apps use ffmpeg & xine.
I am trying to figure out why our company did any of this encryption when it
produced the DVDs (not done in-house) We are a non-profit and, ironically,
the topics of the DVD are open source-like values.
