I changed out my s-video cable from my sat.reciever to my TV with moster video3 cable recently. The picture got better but still pixelated. Is there a better cable from dish to reciever that can be purchased to get rid of pixalation? My signals range from 94 - 100. My reciever is a Hughes HBH-SA. Any info would be great. maybe even better recieve recomendation would be great as well.
