[mythtv-users] Closed Caption MPEG 7?

I have been dreaming of a use for closed captioning for years now. They 
have a box that will scan the closed captioning and 'bleep' out bad 
words and such from a list. I have not every been able to use the box 
because it requires an analog audio signal to mute and I have always 
used digital with the dvd player and sat box. It would be kind of neat 
to have a feature with myth that scans a list of phrases, words and 
mutes the audio for a few seconds if it comes across it in the closed 
caption stream. ;)
