When I try to watch something on watches on it says you are not authorized to play this content. Please contact your provider. Why can't I watch these anymore?
What context are you trying to watch? Some can only be viewed on a Cox network, and some can only be viewed if you subscribe to Cox's sports package.
I tried all of them earlier they all gave me that message for the football games. Now the espn3 games are working. So to get the other games we have to subscribe to another package? My Internet payment is not enough?
Im not exactly sure how it works now, because ESPN has changed what comes included with each package. Basically what ever ESPN offers to providers for free, you get. If ESPN charges extra money, then you need a video subscription with Cox to get it. See here for more info;
