Ohhhhh I see!!YouTube videos to help with the software!
I don't just want YouTube! I want the good films! Jurassic World and stuff.
Yes you do need to update things. You can set a lot of repos and addons to auto update but I prefer to do it manually as sometimes the updates **** things up. Your "normal" TV streams are very stable but the sports ones can be a bit less constant as the devs chase new streams.
