well i have a viewsat plat, i know its no hd compatible but i got it working on my hdtv with better picture and when i went to colourstream hd 1 and the picture and sound were there but the only problem was the picture is in black and white (greyish), and not in colour.
i have the right wires, and ive been playing around but it's black in colourstream.
What connector are you using ? Are you entering your HD set using composite, component or S-VHS cabling ?
I have a VS Plat myself entering my HD set in S-VHS input and everything is fine (and coloured).
My SonicView 360 also enters the HD screen by the component input. Component cabling has the highest resolution after HDMI cabling and my 360 gives me a better viewing experience than the VS Plat.
ya i experienced that i s-video as well when it was loose, but im in hd via component cables and ive got it in as hard as possible but black and white there.
