[vlc] extracting audio : main input error

[Sean Darcy]

Following the wiki I'm trying to extract audio from a DVD on linux 
Fedora 19.

> vlc -I dummy --no-sout-video dvd://dev/sr0#1 :sout='#std{access=file,mux=raw,dst=./file.ac3}' vlc://quit

I also tried using the dvdsimple mrl:

> vlc -I dummy --no-sout-video dvdsimple:///dev/sr0#1:1 :sout='#std{access=file,mux=raw,dst=./file.ac3}' vlc://quit
> VLC media player 2.1.4 Rincewind (revision 2.1.4-0-g2a072be)

FWIW:

> lsdvd /dev/sr0
> libdvdread: No VTS_TMAPT available - skipping.
> Disc Title: MY_TALK_PT_1_DVD_1
> Title: 01, Length: 00:00:43.000 Chapters: 37, Cells: 01, Audio streams: 01, Subpictures: 01

Any help appreciated,
