OK. Still trying to figure all this stuff out. I am working on installing a whole house wiring system. I have a digital cable feed coming in the house, along with a seperate cable modem feed. The video feed goes into a four way splitter and i want to add one more video feed. However I was told I should probably buy an amplifier. So while i was buying the levitron kit I threw in a video amplifier. However when I hook this up the picture on all my tvs gets a ton worse. Are there any resources that anyone knows of to help figure out what I should be doing? I currently dont have any other video feed sources but will next year and then will be adding a modulater for security cameras and a HDTV antenae.
