I can manage reading on youtube, but thats because I pause and just use arrow keys to skip forward 5 seconds,
if the timing of the video is too fast or too slow then yeah I can't really stand trying to read on youtube.
I just checked out their channel before posting the above, and it's acceptable. Still not nearly as good as here but atleast it's readable without being painful.
I remember there was a channel that was posting to youtube each individual square of what think was Tales of Demons and Gods and man did that suck.
