I have problems receiving this channel :

CEEITV, FTA channel on Hotbird (11727V; 27500; 3/4)

the picture is pixelated on DM7025S (GP2 1.70 image).

I have no problems with the picture using another
STB (a cheap Korean FTA receiver) with the same set up.

Does anyone know why it happens on a Dreambox?
