Default [Q] Modded alternative to official Youtube app?


I wanted to ask if anyone here is using an alternate youtube app or a modded one? There were a couple I did try from xda but they dont work properly so I'm guessing not compatible with KitKat.

I was looking specifically for the feature to download the videos in HD (Trailers/Lectures) and obviously full HD playback.


EDIT: Oh and Tubemate does not work :/ parsing error...
