Comments

The current source media file is the file for which the IltmmMediaInfo interface/object gets information. To set the current source media file, call IltmmMediaInfo::put_SourceFile.

The program number is 0-based, so the allowed value for val is between 0 and ProgramCount - 1, where ProgramCount is the value returned by IltmmMediaInfo::get_ProgramCount.

To get the current program, call IltmmMediaInfo::get_CurrentProgram.
