Having Trouble Downloading Movies, Series From Hulu

Hello friends, recently I am having a weird issue while downloading movies, and series from Hulu. I am able to watch the shows, movies but when I try to download this, I cant. Has anyone used this app before? Could someone please help me to solve it? Any help will be greatly appreciated.

I found this article on Google, I am not sure if the info is authentic or not. Can anyone confirm me if this might be helpful or not? I am quite confused getting the point “What Can I Download?” that discussed the link will be activated for 48 hours after playing an episode or movie. What do you think is this information is reliable?
