Apparently the whole libdvd suite is acting hoaky.  I logged onto
a shell as a different user, and tried vlc from the command line,
and got:


libdvdnav: Using dvdnav version 4.2.0
libdvdread: Using libdvdcss version 1.2.13 for DVD access
libdvdread: Could not open /dev/sr1 with libdvdcss.
libdvdread: Can't open /dev/sr1 for reading
libdvdnav: vm: failed to open/read the DVD
libdvdread: Using libdvdcss version 1.2.13 for DVD access
libdvdread: Could not open /dev/sr1 with libdvdcss.
libdvdread: Can't open /dev/sr1 for reading
[0x8f52a88] dvdread demux error: DVDRead cannot open source: /dev/sr1
[0xb3c067f0] main input error: open of `dvd:///dev/sr1' failed


Checking /etc/mtab, things seem ok near as I can tell.

/dev/sr1 /media/IRON_MAN_3 udf ro,nosuid,nodev,uid=1000,gid=1000,
iocharset=utf8,umask=0077,dmode=0500,uhelper=udisks 0 0

Could be some corrupted dataset the libdvd suite looks at, but
it really looks more like the suite.
