Also if using Myth, you have to run 'ivtvctl -w cc' first, before starting
viewing, that enables VBI passthrough, otherwise it won't send this to
the decoder, something that in the future would be turned on by Myth
possibly by either the CC enable menu selection or just automatically
(since that must be for using the OSD to show CC, while this native support
allows a TV's default CC captioning to show it).

Thanks,
