+Apparently libdvdread only works with UDF file systems. I tried to point
+VLC to an ISO 9660 image file, but libdvdread only complained:
+
+    $ vlc dvd://foo.iso
+    libdvdread: Using libdvdcss version 1.2.10 for DVD access
+    libdvdnav:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.IFO failed
+    libdvdnav:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.BUP failed
+    libdvdread: Can't open file VIDEO_TS.IFO.
+    $ file foo.iso
+    foo.iso: # ISO 9660 CD-ROM filesystem data 'CDROM
+
+However, after I extracted the image file to a folder, everything went
+as expected. (Of course also with an image file containing an UDF file
+system :-))
