Here's a partly-edited version of my email exchange with STARZ yesterday.
Is it Starz’ intent that episodes 3, 4, and 5 of Counterpart are unavailable from the Comcast On Demand TV menus? (Both HD and SD menus.). If so, why? I subscribe to Starz thru Comcast and want to watch the series. Thank you.
Thank you for taking the time to contact us. I am sorry your provider has not added this to your On Demand library. While we cannot add titles directly, we would be happy to notify your provider on your behalf, about this issue.
I am surprised to hear you say that you cannot update these episodes yourself on Comcast's on-demand platform. In general, whenever someone complains on Comcast's forum that a particular recent episode from any particular network is missing, a Comcast rep explains that it is under the control of the network (not Comcast) although sometimes their team does contact the network provider to add them.
Thank you for supplying us with the information we need to further assist you. We will notify Comcast of this missing On Demand content. Please let us know if we can be of any further assistance. Thank you for being a STARZ subscriber.
