Or download both videos:
wget http://blip.tv/file/get/Popey-mark1630.flv wget http://blip.tv/file/get/Popey-mark2472.flv
or, if you have a good internet connection, yet the download is very slow (like it is for me), use aria2:
sudo apt-get install aria2 aria2c --split=10 http://blip.tv/file/get/Popey-mark1630.flv aria2c --split=10 http://blip.tv/file/get/Popey-mark2472.flv
And play them locally with your favourite video player.
P.s.: if you get a Windows commercial on top of the UDS-n videos, blame it on Blip.tv :)
Thanks to popey for the videos!
