Those are some silly rules, at this point the episode is yours. The person you got it from shouldn't regulate what you do with it. If he's willing to send it to you, then it should be fine if you can send it to others or do as you please with it. It's not like the episode is his own intellectual property, cause that'd be a whole different story.
Once it's in your hands, you're free to do what you want. It's a public TV show, access to it shouldn't be limited on it, unless someone refuses to trade in return.
