[mythtv-users] Question about Closed Captioning

[Brian Walter]

Greetings,

Where does Myth get the indication of closed captions?  Is it from the 
stream itself, for from the guide?

I'm trying to track down why CC seems to work sometimes, and not other 
times.  Almost all programs indicate that they have CC, but, sometimes I 
can get CC and sometimes not.  When toggling 'T', it will say CC 1 
on...but...no captions.  Just wondering where the information for the CC 
is coming from, and if I need to dig deeper into ivtv/myth/etc.

Brian
