If your not swedish, press "Media" then the instance zone you want and there should almost be a bear tanking pov from most of the bosses
Have fun!
Oh and also, You can right click save where it says "ftp" to download the movies.
Edited: I just noticed theres not alot of bear tanking povs from him, I thought he made more.. But theres a few.
