I've been using this extension for a while now and it works great, but since recently a QR-code is put onto the video when downloaded (if it's a HSL one that needs to be converted). I understand that this converting process can be expensive and I'm willing to donate, but $30 seems like a lot no? The QR-code is not small either, it takes up like 40% of the video, rendering it absolutely useless. Does anyone know any alternatives or workarounds?
