If you give a time and date and what the show was about, maybe the cappers can go back and see if they have the show.
I can't speak for anybody else, But when I see something that I may like, I will go back and play it back as if it was going on now. If I get to an area that looks boring, I just F.F. it just to get through it and most of the time, those shows get deleted.
My advice would be to post the time, show, host, & about how far into that show you are talking about. That way, you may have people that recorded the show to be on the look out
