But the quality of the video seems to vary depending on the program. </div><div><br class=""></div><div>From my testing, I think the Shield TV has it’s own problems. It depends on app. Prime Video has a jumping problem every few seconds. It’s minor but depending on the scene and program it’s annoying. Sling TV does not have this issue. Mythtv does not have this problem on most programs.</div><div><br class=""></div><div>If anyone have the pilot of The Enemy Within (NBC 2/25/2019), the opening has the main character walking toward the camera and a bicycle crossing right to left. In that scene the bike seems to jump across the screen every second. This also happens on Kodi 18 on the shield tv. It does not happen on a Ubuntu desktop with an Nvidia GT710 GFX card.</div><div><br class=""></div><div>i think there are a lot of interactions between the UHD TV settings, the Shield TV settings and Mythtv settings.
