I have a 10m s-video lead running to my TX200, I have tried s-video with three sources. Two work fine but the other has a glitch. The faulty picture is mostly monochrome but there are patches of colour where the colour is a strong one. Anyone seen anything like this before?
The bad source is a Philips 1500 Freeview box and unfortunately it’s the one I want to use

. The box and cable work fine with my CRT.
