The value referenced by pLanguages represents the number of text languages / language blocks for the current DVD or disc side. This value determines the possible values for the Index parameters of the following functions:

IltmmDVDControl::GetDVDTextLanguageLCID

IltmmDVDControl::GetDVDTextNumberOfStrings

IltmmDVDControl::GetDVDTextString

IltmmDVDControl::GetDVDTextStringType

For example, if pLanguages is updated with the value 4, there are four text languages / language blocks. Since the Index parameter of the functions listed above is zero-based, the possible values for the Index parameter is 0 - 3.
