Hi guys I have 2 brand new star s receivers but I'm having problems receiving channels on them, I set these up all the time but just cannot figure these 2 out, when I do an auto scan it it normally picks up over 900 channels but is only picking 544 channels on both boxes, I've tried open vix, atv etc, the tuner configuration is Astra 2E/2F/2G at 28.2°E,any help would be great.
