To be honest, I don't really use DisneyNOW. I only watch the episodes from my television channel. But as far as I know, I think that app is accessible if you are in the United States. Are you planning to watch or record the episode in any way?
Unfortunately, as I said before, the app is only accessible to people in the United States, so I don't think I can help out much with that. I can only help out with the DropBox links that are provided to me each Monday unless if something happens and he is not able to send them on that day. Sorry.
