If there is a mute-function in mythtv (I never looked but there could be)
it should be a 2 line change to implement that option, and another 2 lines
to make it configurable. Why not...

MythTV has been ready for text since 0.7 or before, it just wasn't used.
The frametypes were defined and skipped on playing, I just had to add a
means to code and decode them. Adding another type should be trivial.
As a beside and if you live in Europe (but as you write "close caption" I
suppose you don't :-): MythTV will store _all_ teletext marked as
subtitles, which for a lot of channels means the program information is
there as well. Only sometimes it will be for all channels of the same
