 I am in Australia, my understanding is that closed captions use Teletext
 style character coding.

 The colour of the captions themselves is rendered correctly.

 However, sometimes the broadcaster also transmits codes which changes the
 background colour of the caption to something other than black.

 In particular, a favourite colour scheme is blue characters on a white
 background. Unsurprisingly, blue characters on a black background is
 virtually unreadable.

 MythTV does not render 'background' colour codes in closed captions
 correctly. By the time the 'blue characters' are being displayed, the
 background colour is changed back from white (for example) back to black.
