Thanks, will give this a try. Question: is there a way to get roku to scale what it has to fit? That would save a ton of effort…

For us, it is actually more complicated, our images live out on a CDN and are generated in code, which I just figured out is generating that postage stamp looking image by rendering the original size image centered in a 1920x1080 black rectangle. 🤦‍♂️ Bug submitted, thanks for prompting me to dig to the bottom of it… 👍
