I am always taking notes (with my beloved OneNote ) on tips that I get from video. After I scroll a video back a little bit few times or put it on the pause and resume - pretty much all the time video just freezes with no error displayed.
To solve this I need to refresh the page, start video again and seek to the position where it stopped.
It is really a pain especially taking into account that I have no idea of how to scroll precisely. On the big video (1hr+) seek step are pretty big.
I use Surface RT with Auto video format selection in Channel9 video player.
