@Xezak Welcome! I hope you enjoy being part of the site.
There are probably some specific help pages/comment threads that can answer your question in detail, and I'm sure another Gentle User will step in here and point you there.
For now, let's look at some very general concepts: None of the thousands (millions?) of videos or images featured on the torrent pages are stored by the gaytor.rent website. Instead, individual users (like me, and now you) have some of them on their computers. Think of this website as a "matchmaker," connecting your computer to other computers so files can be shared back and forth between users.
The small "torrent file" you've downloaded from this site isn't a video. It's sort of like a passport that lets your computer connect to the other users so that you can download video material directly from them, and then the video (a much larger file) will show up on your computer.
This requires having a software application running on your computer (a "torrent client") that does the actual connecting-to-others and sharing files. I'm afraid that I don't know anything about iPads, but other users here do and they can probably point you to a web page that has the directions you need. The setup can be tricky, but if you get stuck, don't be afraid to ask questions in the forum. All of us had to learn this stuff when we got started.
Good luck, and again, welcome!
