First, this is my first post here (I have lurked a bit in the past and liked what I saw, so I am joining in to actively participate!). On to my question: I have had my two RCA DirecTV receivers for a year now and I LOVE the picture quality on my primary TVs (hooked to the receivers with s-video cables). However, my SECONDARY Tvs that are fed by coaxial cables are not super clear or sharp and appear "fuzzy". The cable I used to route to these secondary TVs from the receiver outputs was existing RG-59 from the original Time Warner cable hookup (going through a splitter too). Would replacing these runs with quad-shield RG-6 and good ends (like Thomas and Betts snap-n-seal) help to clear this up? I am concerned with the shielding of the RG-59 keeping interference out as all the runs are VERY close to live romex electrical wire (can't really avoid it due to proximity of main electrical box). I know that the receivers are capable (the s-video output looks FANTASTIC and I don't have super high-end expensive TVs by any stretch of imagination). I am aware that S-video is far superior to coax, but I don't think the difference in quality should be THIS pronounced. What are some experienced opinions? Worth the time and expense?
