> Does it play DVD ISO files ? Can you use the menus, etc. ?

Those are semi-loaded questions. It can and does play .vob files, which is enough if you actually just want to watch the video, which is VLC's primary use case.

It is not a full media manager with additional functionality.

It does play DVD ISO files. Just drag and drop them in, hit play.

The question you should be asking is, "does it properly ignore DVD menus?"

The question you should be asking is "can it find its way around DRM?"

When I play some bought DVDs with VLC the DRM stops the DVD getting to the menu stage (on Linux especially) and I need the menu to change the language for my children who don't always want English[1]. Skipping the menu doesn't let me change the language, and not using the skip-menu option means the DVD won't play. Disney are not alone in this, but are the guilty party that comes to mind.

1. Even better when the nordic regional edition of a film has something crazy like Finnish as the default language, and English isn't there at all, but my children want the voices in Norwegian. So skipping menus goes straight to the film in language that doesn't even make sense to Finns. Thanks DVD producers, there isn't enough frustration in my life but with your help and my money we're reaching levels close to 100%.

I was usually able to switch the language by right-clicking, there's a submenu that lets you select which audio stream (i.e. which language) you want to listen to.

antisthenes notwithstanding, VLC does play DVD .iso files and you can use the menus.

Wow - that's fantastic. Thanks.

Yes, with mouse, keyboard, or remote.
