Macbookpro mini dvi-vga to scart problem

hi,

I recently bought a mini dvi to scart cable and i wanted to connect my macbookpro to my tv so i also bought a vga to scart cable.

for some mysterious reason it doesn't seem to connect to the tv.

when i look at the screens in the applebar both are shown though.

anyone know what the problem might be?

grtz
