Subscriber Only Views on YouTube -

i've checked traffic sources on youtube analytics. however, not see checkbox subscriber views i've been reading about. there other way can see views coming subscribers youtube.

in analytics user interface, there (currently - i'm sure change ui) dropdown in top left defaults "subscribed & not subscribed"

via api, haven't been able find equivalent parameters.

the insighttrafficsourcetype dimension give sum of people arrived @ video through various 'subscriber' entry points, isn't same views subscribers.
