DVD menu issue: Known or unknown bug?

[cesss]

After starting this thread: https://forum.videolan.org/viewtopic.php?f=12&t=161302 and being able to find a workaround, I believe the problem is not Mac-specific, but general. I'm not sure if the problem is in libdvdnav or in libdvdcss, or in other place. It can be summarized as this:

• I've experienced it in just some specific DVDs I bought years ago. I copied their VIDEO_TS (they don't have AUDIO_TS) to a hard disk, and I'm playing from the HD.
• When opening the HD folder with VLC media player, no video window appears, and you hear the audio of the DVD menu, but crippled.
• If you wait some time, the autoplay feature kicks in, and then the video window appears, and you can watch the movie with perfect video and perfect audio. The same happens if instead of waiting for the autoplay, you select "Title 1" from the VLC menu bar.
• Now, if you drag the playback slider to a point somewhere in the middle of the movie, and then you select the "DVD menu" from the VLC menu bar, now you see the DVD menu perfect (the audio is not crippled anymore, it's perfect, and you see the DVD menu with no problems at all).
• If you didn't drag the slider, selecting the "DVD menu" triggers the problem again (the video window disappears, and you listen the crippled audio of the menu.

I tested that it also happens with VLC 1.1.12, so it's not something introduced in the latest versions, but seems to be there since a long time ago.

Is this bug known? Can I help in some way for it getting fixed? How?
