Been having some cable signal issues on my Premiere for a little while now. Signal strength sometimes dips to around 30 db and high 50's, with some pixelation. I've attached a pic of my current setup. The cable goes into a 3-way splitter, which feeds a TW HD box, TW HD DVR box (Luckily I don't have to use the TW boxes lol), and then into another 3 way splitter, which feeds my modem/phone adapter, Premiere/Tuning Adapter, and another TW HD box. I'm wondering if maybe 1 large powered splitter might provide a better, more stable signal? I've also attached a pic of what that would look like. Ideas?
