1) The DM 500-Si is the first Linux based DVB Receiver. This receiver runs on open-source

software developed by hundreds of developers around the world. This is the ultimate

machine. It has many different skins that can be applied to make the user experience

completely customize. If you're looking for a VERY powerful Dreambox DM 500-Si， and

something to have fun on， this is Dreambox DM 500-Si for you.
