This method selects the default language and format to use for subpictures and menus when the disc is played. For example, if Language is specified as 0x409 for U.S. English and subpictureExtension is specified as DVD_SP_EXT_Caption_Big, the DVD Navigator tries to show U.S. English text in the "big caption" format in subpictures. If the default language or language extension is not found on a disc, the DVD Navigator selects the closest match.
