I have noticed that the quality of picture when watching TV3 on SKY is poor compared to other channels. Sometimes I think I am watching clips from PS3/ Xbox games as opposed to reality. Is it just me and my deteriorating eyesight??!!
Your dish may be slightly off perfect alignment.I had problems getting CNBC and thought it a News Corp plot until I had a technician realign my dish.Several channels that had offered poor reception were suddenly perfect.It transpired that my dish had been moved slightly by winds, heavy rain etc.
