Bad news. I wrongly assumed that DVD-audio used CSS. It actually uses a thing called CPPM, and cannot be played on Linux. There are now windoze players. See "DVD-Audio's CPPM Circumvented": http://it.slashdot.org/article.pl?sid=05/07/06/1740206 I was playing with the AC3 audio from HD-TV, which mercifully is not encrypted. yet.
