I'm not sure if this is a hardware acceleration thing or not, but all the NHL on TNT broadcasts are being played back under 60fps and the picture isn't very crisp. I primarily watch on a Nvidia Shield but it's the same when watching in the browser. I assumed it was just a TNT thing in general but streams of questionable means look way better. This is with FiOS credentials.
I've had this issue across both servers I've used, one being a NUC with onboard Intel graphics and one being a custom PC with an Intel Arc card which I'm currently using. Hardware transcoding debug info is below if it's related. This is on version 2025.02.19.1823 in the latest Docker image.
