I haven't experienced any problems even with very old TVs caused by the
higher video signal bandwidth.

you can use any VGA2SCART cable realizing some composite sync circuitry.
My favorite cable (the simplest circuit I know from) is described in my README.
I don't know why most VGA2SCART cables are composed of so many parts.

ATI cards do have a major drawback compared to Intel cards:
They can't scale vertically in interlaced mode because they can't scale
both fields independently. So your TV must handle format adaptions.
