OK. Copying the DVD to my hard drive works, provided I do it as root. I
need root because the top-level directory on my DVD has *no permissions
whatsoever*. The files within this directory, though, have reasonable
permissions for user, group, world. But the uid and gid are -1.
VLC will only play the first program in the files so copied.
To get the rest, I use a program I found at http://www.pixelbeat.org/docs/
DVD-VR/ which links to http://www.pixelbeat.org/programs/dvd-vr/
It reads the IFO and VRO files and puts together a sequence of VOB files.
VLC will play these VOB files.
I've used more disk space on my laptop this week than I've used in the
previous year, though -- essentially two copies of the data on the DVD.
It wold be good to find some way to combine all this hackery so as not to
need all that file space.
