I can't seem to be able to watch a show from my On Demand menu. I'd like to watch Game of Thrones but for some reason, I don't have the option to "play". Just "add to wish list" or to continue browsing. Am I doing this wrong? Or is there no way to actually watch it? The guy that installed everything didn't really tell me a lot about how the equipment or programming works, so I apologize if this is a dumb question.
