Remarks
This method selects the default language and language extensions to use when the disc is played. For example, if Language is specified as 0x409 for English and audioExtension is specified as DVD_AUD_EXT_NotSpecified, the DVD Navigator will look for the basic audio stream in English. If audioExtension is specified as DVD_AUD_EXT_VisuallyImpaired, the DVD Navigator will first look for a special audio stream in English for people with low vision. If the default stream is not found on a disc, the DVD Navigator will select the closest match.
