Ok. Thanks for the info.

But I was trying to use file://. I tried:

- Media > Open File, (clickety-click), Play

- Media > Open (advanced), Add, (clickety-click), Play

- Media > Open Network Stream, URI:
file:///home/jje/Videos/test/VIDEO_TS/VIDEO_TS.IFO, Play

- command line, ./vlc file:///home/jje/Videos/test/VIDEO_TS/VIDEO_TS.IFO


...and in all cases, each time VLC changes the file:// to dvd://
somewhere during the opening process, without any user interaction. The
Recent Media menu saves the given URI with file://, but while opening,
it always gets converted to dvd://.

Here's an excerpt from the log:

So far, so good... but then immediately the next lines say:

---8<---8<---8<---

[0x9bfd9b4] main playlist: stopping playback
[0x9bfd9b4] main playlist debug: deleting item `VIDEO_TS.IFO'

---8<---8<---8<---

...and then the log continues like before. It seems opening the .ifo is
creating a dvd:// request?
