I have a samsung A series 26" 720p telly...
I've hooked up my A1200 via similar RGB->Scart cable from the video port.
The picture is very crisp, however there is an intermittent wobble(side to side, as if the screen is trying to reset or something...)
It's pretty annoying to be honest!
I can make it go away by switching to NTSC modes on the Workbench, but games and such like still have a wobble.
Do you have any idea why it does this, because otherwise the picture quality is superb...
