DVD .iso file Menu Freezes
Initially reported as Kodi bug on Android, but the exact same issue is seen in VLC on Windows. I was advised to report it here.
Bug report Describe the bug
Here is a clear and concise description of what the problem is:
Playback of DVD .iso file for commercial DVD of 13 Ghosts. When the disc starts, the Main Menu has several options, including Play Movie, Scene Selections, Special Features, and Languages. If you try to select a Language, the Main Menu reappears, nothing is highlighted, and the menu seems frozen - the arrow and select buttons on the remote do nothing.
This is a bug because you cannot start the movie or go to any other menu option. Expected Behavior
Here is a clear and concise description of what was expected to happen:
In a normal DVD player, when you select the Language option, and then select any language or subtitle, the Main Menu reappears with the Play Movie option still highlighted, and you can continue to move the focus up or down to other options or just start the movie. Actual Behavior
Initially the Play Movie option is highlighted and you can use the up/down arrows to move the selection to any other item. If you go into Special Features and then return to the Main Menu, all is fine and you see the Play Movie option again highlighted - this is all fine and correct so far. The bug shows up if you go into either Language or Scene Selection and select a language (or even just go back to Main Menu), the Main Menu is displaydd, but no highlighted cursor selection and the entire UI for the menu is frozen. The background music continues to play, but pushing any arrow button or the OK button on the remote does nothing at all. At this point, the ONLY option is to press the back button to return to the Kodi file selection screen and then re-select the file for play, at which point the disc starts over. Possible Fix
**The key to this problems seems to be that when returning to the Main Menu from either the Languages or Scene Selections sub-menus, there is no focus or highlighted option shown on the Main Menu, so nothing happens when you try to use the remote arrow buttons to navigate around the Main Menu.
I will note here that on my Windows computer, the VLC media player shows the exact same menu bug on this disc as Kodi does on my Android TV Box (no focus when returning to the Main Menu), BUT, this does not present a problem on the computer because using the mouse to move the cursor over any of the four Main Menu options brings up the focus highlight, and then the menu functions normally again using the arrow keys.
The significant difference is that on Android TV without a mouse, there is no way to move the non-existent cursor over one of the menu options to restore the focus, thus the entire Main Menu remains frozen.** To Reproduce
Steps to reproduce the behavior:
Start the disc play from an .iso file (or probably even an attached DVD player)
Select Languages from the Main Menu
Return to the Main Menu and see that none of the four options are highlighted and the remote arrow and selection buttons do nothing at all.

Here are some links or screenshots to help explain the problem: Additional context or screenshots (if appropriate)
Here is some additional context or explanation that might help:
Note that this same .iso file plays the menus perfectly using an old Asus O!Play media player, so the problem is not a bug in the .iso copy.
Here are several other differences noted between normal menu operation on this disc and this bug:
When Languages is selected from the menu, the Languages screen NORMALLY shows nothing selected, and the "Main Menu" option at the bottom is highlighted (the option to return to the Main Menu screen). But with this bug, when the Languages screen comes up, the "Francais" Subtitles option is highlighted.
When you choose Scene Selections" from the Main Menu, the NORMAL initial focus on the Scene Selections screen is the "Start Movie" option, and if you instead choose "Main Menu" you are returned to the Main Menu with the Play Movie option highlighted. But with this bug, when the Scene Selections screen opens, the initial focus is on Scene 2, and if you instead choose "Main Menu" you are returned to the frozen main menu the same as happens if you go into the Languages screen.
NORMAL menu operation on this disc is that any time you return to the Main Menu from a sub-menu, the focus is on Play Movie (highlighted). But with this bug, that normal operation is only seen when you return from the Special Features sub-menu.
