I missed this file.  Thanks for pointing it out.  But I don't think US closed
caption is working.

I've tried "T" during programs for which I know there is closed captioning
(checked it on my real TV).  But couldn't get closed captioning to show on
MythTV using the "T".  I tried this on both Live TV and recorded.  (My Live TV
is still in slow motion so this test may not be valid.)

>From the code in NuppleVideoPlayer.cpp and NuppelVideoRecorder.cpp, it looks
like US captions haven't been implemented yet (search for "caption" in these
files).

rtframeheader in format.h defines a code for US closed caption.

globalsettings.cpp and backendsettings.cpp have some close that looks like it
could be used to set for US closed captions.  So I set Vbi format to "NTSC
Closed Caption", restarted the backend, and still didn't get captions.

There were also two threads on the MythTV Dev list in Jan. 2003 which interpret
as meaning that US closed captioning isn't supported yet.
