Wanted to bring an issue I've been noticing a few times as of late I've been having with my Nvidia Shield (Pro 2019 model).
While watching sports, specifically basketball has been each time I've noticed this, after some time the video will start to stutter, skip, and slip out of sync after some time during the game. To fix this, I can either just jump back and then back to live, or exit out and enter the video once again. I did send in an e-mail about this right after hitting Submit Diagnostics on 1/6/2020 but did not hear anything in response.
At that time, I was running off of Wi-Fi and figured that might be the issue. I changed to an Ethernet connection and the issue still occurred just last evening. I did not hit submit diagnostics at that time. This is totally a new issue as I mainly watch only sports and this hadn't happened prior to a few weeks ago. Any help would be fantastic, thanks so much!
(Also, as an aside, my Pixel 3a XL in the last week or two has decided to play any Channels DVR video in stretched full-screen, whether it be in portrait mode --yikes!-- or landscape. Just thought I would throw that out there!)
