Seems that the apt source for libdvdcss2 listed as

deb http://www.videolan.org/pub/videolan/debian $(ARCH)/
deb-src http://www.videolan.org/pub/videolan/debian sources/

are giving an error. Went to apt-get.org (thanks to the forum) and found that these worked:

deb http://download.videolan.org/pub/videolan/debian woody main
deb-src http://download.videolan.org/pub/videolan/debian woody main

Is this something that I did wrong? Got the DVD to play after getting OGLE, XINE wouldn't work.
