Shack video streams always a bit too slowly for me, so I went to watch it on youtube.
I set it to 720p, and let it download for a bit while I played bejwelled. When I switched back to the window, the download was complete, so I clicked play. I then clicked 'pop out' by mistake, instead of hitting 'full screen'. I then closed the pop out window where it had started downloading from the beginning, and then I noticed the main window had lost all the download progress as well.
wth... I hate youtube sometimes.
Anyway, that does look promising.
