I have very slow mobile internet so I prefer to download some videos in hd and store in my pc for offline viewing later. But as I have a small screen smartphone, I can't enjoy learning on that. I Wonder why did even i bother to purchase bundled courses here if I can't use any of them. No way to watch videos on computer, can't Chromecast either. You could've made a windows software where videos can be stored in encrypted format. Anyway, I Won't use this service again.
