I just saw this invention on The Register, which matches keywords from the subtitle track of the tv feed, and automatically mutes the TV. I was thinking that there really ought to be a MePo plugin to do this job. I couldn't find anything from a quick search; ss there anything already existing to do this, and if not, does it sound possible? Ideally you'd be able to define strings to match, with a corresponding action and period to perform it for; e.g. if detect string "compare the meerkat" then mute, duration 40 seconds.
