dvdrip problem

[François Patte]

Bonjour,

I try to use dvdrip but I have some problems with libdvdcss and libdvdread: when
I want to rip a selected title I get this quite cryptic message:

transcode v0.6.12 (C) 2001-2003 Thomas Oestreich, 2003-2004 T. Bitterberg
libdvdread: Using libdvdcss version 1.2.8 for DVD access
libdvdread: Couldn't find device name.
libdvdread: Can't open file VIDEO_TS.IFO.
[import_null.so] v0.2.0 (2002-01-19) (video) null | (audio) null
[import_vob.so] v0.6.0 (2003-10-02) (video) MPEG-2 | (audio) MPEG/AC3/PCM |
(subtitle)
[export_null.so] v0.1.2 (2001-08-17) (video) null | (audio) null
[export_ppm.so] v0.1.1 (2002-02-14) (video) PPM/PGM | (audio) MPEG/AC3/PCM

So what can I do?

Thanks for any help
