Televisions, DVDs and Video recorders
Scart plugs (often called Peritel) are widely used in Spain meaning that televisions and DVDs can quite easily be connected. HDMI is also standard on all new Spanish televisions and DVD players.
UK televisions can normally be used in Spain. Older sets may be able to receive the PAL picture but not the sound. Modern sets are often fine as they accept multi-standard signals. Television sets from countries where the standard is NTSC or SECAM will not work on the Spanish PAL system, unless you run the signal through a multi-standard video or DVD player.
In 2010 Spain is expecting to be fully digital with television transmissions. This means that almost all UK sets will be 100% compatible.

Fitting Sky television in Spain
Although, according to Sky's contract terms this is illegal, it is common practice for residents in Spain to have Sky fitted. There are lots of installation companies but choose carefuly. You will probably need a dish of at least 1.2m diameter. You will need to have a UK address to register with Sky. If you do not have this then your installer should be able to provide a card for you but expect to pay more for this. Free-to-air channels using ASTRA may need a larger dish. Sky boxes purchased in the UK will be fine to bring to Spain with you and can save you a a lot of money.
Computers from anywhere in the world will be fine in Spain. You will have to change the power plugs of course. You will also need to chage the system settings to take account of the new time zones etc. We would highly recommend that a power surge unit is fitted to your computer power supply. The current in Spain varies from time to time and is often cut or has major spikes.
