HBO On Demand

There is a separate category for HBO HD OnDemand, It may contain less content, but it is there.

You might also look into getting a device that supports HBOGo, like a Roku.

HBOGo has available every episode of every HBO series and documentary in HD and many, many movies, much more content than the OnDemand available on a Cable box.

A cheaper solution may be Chromecast. Just got HBO Go support last month. Can't beat the price tag at 35$, even if its not highend as the more exspensive media boxes.

Good suggestion, but you must also own a tablet or smartphone, Ipad or Android.  I just got my mother a Roku, much easier for her since she has no idea what a tablet is and no smartphone.

Ahh, I see your right. Darn.
