Paul,
You set was designed to work with the PAL I system and not the PAL B/G which is used in Spain. This is a problem facing many ex-pats taking their sets into Europe where the TV systems vary greatly. If you had a Sky subscription in the UK you might want to take your decoder and dish with you. We receive UK TV on a Sky Digibox in SW France using a PAL system I set. The following link is to an excellent e-book which shows you how this can be done (legally)http://www.satcure.co.uk/installing_sky_digital.htm
Cheers,
Andy
