IDvdControl2::ShowMenu method (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The ShowMenu method displays the specified menu, if available.

Remarks
The Video Manager Menu (VMGM) should be accessible from the Title or the Video Title Set domains. The Video Title Set menus (VTSMs) might only be accessible through the VMGM. Any submenus under each VTSM (for chapters, angles, and audio and subpicture streams) are only accessible through that VTSM.
This method is demonstrated in the DVDSample application application in CDvdCore::RootMenu and CDvdCore::TitleMenu.
