[mythtv] Closed Captioning?

[Johann Klemmack]

Does MythTV (or V4L for that matter) support closed captioning?  The bytesex
homepage doesn't list it, and the best hit I got off google was
http://toonarchive.com/v4l-cc/.  Perhaps onto the todo list?  I'd be willing
to help out on this, but I wouldn't know how to get a scrolling textbox
overlay.  Recording the text to DB would be spiffy too, and I have an idea
of how to do that :)
