Artisan Lx Media Center.Having trouble finding sky network!!

[katerson]

Hi everyone
Just purchased a Artisan Lx media center and i'm having trouble finding the Sky programmes.I can get bbc,itv,channel 4 and channel 5 on the analogue connection but for the life of me i cannot find Sky even after hours of boring tuning!I currently have my hitachi plasma connected to my media center via dvi and my sky digi-box is an Amstrad which i've had for about 4-5years.If you anyone out there has a solution for my problem i would love to hear from you.Many thanks for your help.
