In the course of scheduling the video premieres on our YouTube channel, I learned that YouTube only offers time options on the hour and every quarter hour after. Since a few of the talks were listed on the website schedule as starting at :10, :20, or :40, I've had to adjust them 5-minutes back or ahead. The affected talks are:

Nov 21
Alexandru Militaru: from 17:20 UTC to 17:15
Mathias Lang: from 19:10 UTC to 19:15

Nov 22
Mathis Beer: from 15:20 UTC to 15:15
Ali Çehreli: from 16:40 UTC to 16:45
Stefan Koch: from 19:20 UTC to 19:15

I've got a blog post coming shortly describing how to participate, with all the necessary links.
