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. ;)
