My thanks to Rosario for raising this, I am looking into HD receivers for most of the European countries, as yet there really arent enough channels on HD ( much like our own FreeSat ) to make it good value for money.
The picture quality is great and the improvement over SD (standard definition) especially on a very large LCD or Plasma tv is outstanding.
At the moment there are no free channels in HD from Spain, only the Digital+ & Canal + spain, ones which are encrypted in various formats – NagraVision 3 and videoguard – and which require a dedicated receiver ( again like our Uk sky) where the viewing card is matched with the receiver by the broadcaster.
Some cards may be available with set top boxes but usually at extortionate rates in this country. To go through official channels to obtain one you must have a spanish address.
