My Apple TV app on Directv Streaming device stretches video vertically. All other content and apps are correct and TV Aspect Ratio is correct at 16:9. TV is an LG, but as stated all other content works perfectly.
Same issue here with the Apple TV app on a DirecTV Streaming device.
The video is stretched vertically, but all other apps and content display correctly on the same TV. YouTube, Netflix, Hulu, and regular channels all preserve the correct aspect ratio, so I do not think this is a TV setting issue.
I also tested the same Apple TV content on my PC, and it displays correctly with black bars at the top and bottom. This seems specific to the Apple TV app on the DirecTV Streaming device.
