Clear enough, but the device is there, VLC plays it. Even more: in the  
example run with dvd://1 I sent, you can see that the device is there  
and dvdnav/dvdread gets to it. Here it is:

You are right about the missing /. In fact, if I play from / the  
device is found. Can it be a bug in stream_dvdnav that strips the  
leading / ? Any ideas?

Also, have you got any idea as to what those errors mean:

> *** libdvdread: CHECK_VALUE failed in nav_read.c:356 ***
> *** for dsi->dsi_gi.zero1 == 0 ***


Finally, what's best to use, internal or external dvdnav/dvdread/dvdcss?

Thanks
