help..knowledgeable "geeks". (Said with the utmost respect) I have a wifi router that I can plug a 1TB hdd in and hubby and I can watch different movies on our iPads at the same time. If we both want to watch something at the same time, we plug the hdd into the TV's USB port. If I buy a chrome cast gizmo, will that allow me to stream the movies from the hdd in the router to the TV? I am trying to avoid having a PC in between. I am guessing there is an app that controls the chrome cast. Am I on the right track?
