You Tube sign in

Hi I finally upgraded my 9200 for the HDR FOX T2. I have to admit it is great. I also updated the firmware so I know have sky player working a treat so I can watch the F1.

However, with the you tube app I would like to be able to sign in with my account. That way I could watch my favorites or videos that I have posted.

Is this possible to do?
There is no guarantee your favourites will be available even if you did log in - I can't find some of mine via the TV portal anywhere in the search even though the same search on a PC brings them straight up. YouTube are doing some kind of content filtering according to client device.
