libdvdcss auth problems

[Javier]

Hello !

I have compiled sucesfully  vlc 0.2.91_2001-11-14
I have compiled libdvdcc 1.0 ( older lib doesn't worked better  )
vlc works fine whith non scrambled DVD ...
But i get this error whit crypted DVDs :

libdvdcss error: ioctl_ReportAgid failed, invalidating
libdvdcss error: drive would not authenticate
dvd error: dvdcss can't open device


libdvdcss 0.03 said :

libdvdcss debug: GetASF not authenticated (ASF=0)
libdvdcss debug: requesting AGID
libdvdcss error: drive not authentic
libdvdcss debug: fatal error in CSS Init

I have tryed DeCss testdvd, and i get similar response -> drive cannot 
authenticate

Any ideas are welcome ;-)
