I had most probably a similar issue, /dev/rdvd was missing on my system.
I did not however try to bisect the git tree, I'm running plain 1.4.0.

I got ride of the issue by setting
""
media.dvd.raw_device:/dev/sr0
""
in the ~/.xine/config file.

I guess creating /dev/rdvd or symlinking it to a device that exists
should work too.

Does a similar trick help for you ?

You can get more logs from libdvdcss by setting DVDCSS_VERBOSE=2 prior
to running xine.
