I just ditched Bright House Cable this morning. I replaced it with DirecTV Xtra tv service. Could someone recommend a reliable DirecTV app for Windows 8.1 Pro w/Media Center x64 and Windows 8.1 x64 ? I found a actual DirecTV for my Nokia Lumia 521 w/Windows Phone 8.1 in the Windows Phone Store. The DirecTV app's in the Windows 8.1 Store all appear to be generic app's, not actually from DirecTV. Which of those are reliable and actually work ?
