digibox connection to infocus 7210

[mastaff]

Hi All,
I am probably missing something very obvious here but advice badly needed. I have connected a Pace NTL digibox to my Infocus 7210 with a Scart to S-video lead (input 4 of the projector) and regular phono lead to the amp. Picture quality is OK except it is black and white. I cannot get it to come out in colour. Am I missing something very obvious here.
All help gratefully accepted.

You probably need to change the video output mode of your digibox in one of the menus.
