CinemaNow on Xbox One: Intermittent stuttering and missing UV movies!

[PCFan]

Recently I decided to try the CinemaNow app for Xbox One. I was having issues with the Xbox One's Vudu app and I hate the interface that's why I wanted to try out CinemaNow on my Xbox One for my UV movie collection. I'm missing at least 8 movies in my CinemaNow library, not counting Disney Movies Anywhere and the non-UV Vudu-only ones. Also about every 15-20 seconds I get a quick stutter in the video. Stuttering was worse on the Vudu app. The only streaming app that I don't get stuttering on in my Xbox One is Netflix but I used to get stuttering on that app as well before one of the system updates or Netflix updates on my Xbox One last year. Now that I have the issues I mentioned with CinemaNow on my Xbox One, I'm either going to have to look for another device just to dedicate to streaming Netflix and Vudu and leave my Xbox One just for gaming or move to an Apple TV and switch to iTunes as my primary digital movie provider. I also get stuttering in Microsoft's video service with my movies on my Xbox One and with the Plex app in my Xbox One. Only Netflix on my Xbox One provides smooth video. Is something wrong with my Xbox One?
