I will assume that showing the table of contents for a media clip is more of a feature in your product rather than your product itself. I would not remove a feature just because the competition also has the feature. I would remove it if the feature isn't critical to the central idea, the main motivation behind the product. So in that sense, the competition is irrelevant in this discussion as long as your central idea is reasonably unique.
