knoppix is a very very great distro. (only drawback there is no 64bit version!)
if you get the dvd version you get a package full of interesting things.
i came across minitube which is kind of the watch-youtube-as-tv-programm… and not only that! it can download youtube videos as well!
apt-get install minitube;
# install vlc player
apt-get install vlc;
