[Suggestion] Add info about DVD menu.

[maplee0]

Hello!
Thank you for open source dvd_info CLI app.
It's simple and works perfectly fine in Linux, so now wine isn't needed.
It shows exact info, but doesn't add info about DVD menu.
For example, here is log of dvd_info:

$dvd_info "/tmp/dvd" -v -a -s

As we see, video and audio info are the same, but second log contains Menu info for chapters.
Thanks!

@maplee0 ah my apologies for not responding, this flew under the radar.

I'm a bit unclear on what it's reporting, to be honest. dvdnav navigates the menus, which isn't necessarily related to the tracks, because it can bounce around.

I can see this:

* Menus Information * VIDEO_TS Menu Video: PAL 16:9 (720x576) VBR Auto Letterboxed English Language Unit : Title Menu

which says that's where it's starting, but I don't know how that's relevant, or honestly what it's even displaying.

So ... what are you trying to do, exactly? I'm lost, sorry. :(
