Well that would explain it! I must have done that when I was messing with getting it working the first time. Been so long I completely don't remember doing it, but thank you for your response. Feeling pretty dumb right now!
Does anyone know what the "Force HW Acceleration" setting is when you edit the container? My assumption is maybe it's intended to keep your hardware transcoding enabled through updates so you don't have to manually modify files, but I can't find any documentation about it. That's probably hopeful thinking, but figured I'd see if anyone knew. Thanks for any input!
