Loop Playback

Black Hole

May contain traces of nut
Anybody know how to make an MP4 that loops playback, or make VLC (PC) loop the playback of an MP4? Failing that I suppose I could create a .bat file to repeatedly play the MP4.

(No, obviously I don't mean concatenating a whole load of copies of the MP4 together in a big MP4)
For Windows Version 2.0.0 of VLC the option is at :-
Tools >> Preferences >> Show Settings = All >> Playlist >> Repeat Current Item
Thanks for those, I'm not looking at the PC at the moment so I don't know which version of VLC I'm using (it will be out of date!) but I didn't spot a toolbar icon.

The menu system on a DVD can be used to create looped playback (in fact the menu system can be used to control all sorts about playback - making sections play repeatedly like a verse and chorus - but I have never found non-pro software which accesses the full capability), does no file format offer similar?
The only non-DVD format that I have seen a repeat loop option in, is for animated GIF files, but even if there is a repeat option for an MP4 file, the player would still need to read the flag, so it would be down to the player to handle it
