Yelo TV is a Live TV streaming service for Telenet customers in Belgium. Sadly, it uses Silverlight. Using Firefox and Pipelight, this service works perfectly fine on Ubuntu though:
sudo apt-add-repository ppa:ehoover/compholio sudo apt-add-repository ppa:mqchael/pipelight sudo apt-get update sudo apt-get install pipelight
Then restart firefox and it should work fine.
