And now the stats of a 'commercially produced' dual-layer DVD
(again recorded in UDF file system), containing over 6gb of files.

[in this case the movie "Ice Age, Continental Drift"]

root@glennmcc:~# mount /dev/sr0 /dvd
mount: block device /dev/sr0 is write-protected, mounting read-only

root@glennmcc:~# mount
/dev/sda1 on / type ext4 (rw,commit=0)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
tmpfs on /dev/shm type tmpfs (rw)
gvfsd-fuse on /root/.gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev)
/dev/sr0 on /dvd type udf (ro)

root@glennmcc:~# ls /dvd/VIDEO_TS -l
