Or you could put the effort into improving our support for the newer 708 
captions.  :)  (Does anyone know how much longer the FCC is requiring 
608 captions?)

Thanks for the clarification Gregorio.  I didn't actually trace the code 
to see if we actually pulled the color info when I stumbled across that 
transposition, but figured it needed fixing anyway.  (After all, it 
would have been annoying to /try/ to find that typo when someone was 
adding support for the color codes later--at least I would have assumed 
when things didn't work that it was my new code rather than existing 
code that was failing.)

Guess that means, though, that in MythTV it's actually 100% of 608 
captions that use white.  :)  We fall into the proud heritage of, "Color 
(non-white) characters, while possible, are only occasionally used due 
to the 13-year legacy of set-top decoders which cannot display colored 
captions," (from http://www.netcapinc.com/index-4.html ).
