Experiencing major pixelation on my Elite on a few different channels periodically. Also experiencing it on a Series 3 in a different room every so often. Cable company has a 3 way splitter in the box outside. I also have a 2 way splitter where it comes into the main room. One to the Elite and one to the broadband connection. Any recommendations for a better splitter to put outside? Should i also get a better one in the main room? I have also seen mention of amps, but don't know much about them. Should I get one of those instead? Where should I put it? Thanks!
