I agree it leaves a lot to be desired but you can subscribe to channels through it. Heres how, find the video you want to subscribe to and push the blue right arrow next to it, (not the description or the video itself) then you should come to a screen that has that video and description plus a few more options (add to favorites, add to playlist, share video) again push the little blue arrow on the right of the screen, now push more videos, scroll down and see subscribe to "whatever"......Yes this is beyond tedious just to subscribe to some ones youtube channel but oh well....hope this helps...
