I need to make a 10m video cable with RCA's at each end to take the composite OSD signal from my processor to my TV. The Svideo out is used for the PJ but I don't want to have to put that on to fiddle with the pro's settings. What cable should I use? Would standard coax be OK? Quality is of little importance as long as I can read what's on the screen. I can get cheap RCA plugs from maplin.
