ON DEMAND - New Items

I frequently turn to "On Demand" to find non-PPV shows/movies that have been added in the last week.  In most cases there is not a section(s) for new shows/movies) in the ON DEMAND listings.  I must add that it may just be some sort of oversight on my part in finding new shows/movies for non-PPV.

How do I find what new Premium (HBO, or Starz, or Cinemax, or Encore for that matter...) and Primetime ON DEMAND content that has been added within the last week?   TIA
