Detailed Description

ISO 639-1 and ISO 639-2 support functions.

ISO 639-1 is the two letter standard for specifying a language. This is used by MythTV for naming the themes and for initializing the Qt translation system.

ISO 639-2 is the three letter standard for specifying a language. This is used by MythTV for selecting subtitles and audio streams during playback, and for selecting which languages to collect EIT program guide information in.

In many contexts, such as with translations, these language codes can be appended with an underscore and a 2 digit IETF region code. So for Brazilian Portugese you could use: "por_BR", or "pt_BR". Or, you could specify just the language, Portugese: "por", or "pt".
