| VFW_E_DVD_OPERATION_INHIBITED | Requested action cannot occur at this point in the movie due to the authoring of the current DVD-Video disc. |
Remarks
This method returns an error unless the domain is DVD_DOMAIN_Title. For more information, see DVD_DOMAIN.
This method does not return languages for menus. This method sets the value pointed to by pLanguage to zero if the stream does not include language. Call the Win32 GetLocaleInfo function as follows to create a human-readable string name from pLanguage. LOCALE_SENGLANGUAGE is the locale information type, pszString is a pointer to a buffer to receive the requested data, and cbSize specifies the size of pszString.
GetLocaleInfo(*pLanguage, LOCALE_SENGLANGUAGE, pszString, cbSize);
