The videos look like they are loading but never quite load.

I shouldn’t have to resize all of my videos to 640x480px for a player to work on a mobile device. That would take hours and hours of work (I have hours of video that would need to be readjusted, resized, and reuploaded to the internet while people are simultaneously going through my course).

Is the only solution going to be having to do a bunch of work on already working videos to resize all of them, repost them, and then the people watching the videos on their computer would be forced to watch the videos in lower resolution?
