Its easy, with PSVue or with You Tube TV, they both have DVR. I think if I remember right with PSVue, the recording only stay on for a month. With You Tube TV, they stay for as long as you want.
I personally have liked You Tube TV better as I have used both. The interface is nicer, I like the home screen where it learns what you like and pulls up shows you watch so you don't have to go hunting through the guide for them. I also like with sporting events you can pick a team with You Tube TV and it will record all that teams games. I set it to record all Cubs games, Hawk football and basketball games. It is pretty slick.
