The background disappears of Menu

[melon]

I looked for a thread in the forum, but I can't find it.

Phenomenon (BD menu background disappears)
1. Press any jump button on the menu.
2. The background disappears and turns black. (a short period)
3. Jumps to the specified chapter or title normally.

I did many BD authoring, but there are titles where this phenomenon occurs and titles that do not.
I can't find where the difference is.

Please tell me why and how to avoid it.

This implies that the Blu-ray in question is HDMV authored using the Interactive Graphics method - these always go to black between pages.
The only way to avoid this is to author using BD-J method.

Sorry for the late reply.
I understood it well. Thank you very much.

It will have to be a combination of commands.

Please explain from where do you want to jump to the menu from a title, a VMG menu, VTS menu and in which domain the target menu is VMG, VTSM?
