Regarding 1:
The video works fine even without any JavaScript by changing the Mozilla
browser's user agent to an Android browser via the add-on "User Agent
Switcher" (I used the user agent "Galaxy S II - Android 4.0.3 - Mobile Safari
534.30") and using the add-on UnPlug (UnPlug also provides a URL without
changing the user agent, but it is rtmp which I couldn't download using
rtmpdump). The URL can be downloaded using e.g. axel (wget complained that
the name was too long), which downloads a file of size 225.2 MB called
"37-20091023-Mok-Jinseok-vs-Won-Seongjin-Korean-Baduk-League-eng-sub-b-480.mp4".
A brief skim through the video shows some sort of board game.
