No ad blockers of any sort. I have tried on other systems and no matter what browser or OS I use I never seam to be able to view the feature. Is there a minimal number of views your video needs to receive before this is activated? I wasn't able to find anything about a minimal number in the youtube help area, but I am running out of other ideas.
