I need some input on getting the best video signal from my Dish receiver to a RPTV. The receiver is approx 35-40 feet (cable routing distance) from the RPTV. I currently have the receiver sending the video signal to the RPTV via RG-6 (out of the composite output on the receiver). The pic is quite fuzzy. I am considering running an S cable but am concerned about the length of S cable required (some sources don't recommend an S cable over 15-20 feet). Another option is to split the S signal into the L/C signals via a splitter and send them over two RG-6 lines that are recombined at the RPTV. Any input on these options (or others) is appreciated.
