Connecting a PC to a TV (VGA to RCA/SCART or HDMI to RCA)?

[any ANONYMOUS forum user]

Hi,
I have an ATI graphics card in my pc, it has VGA D-Sub out, and HDMI out.
My TV is a fairly old fellow, but he's reliable, and it has Scart in and the 3 RCA sockets on the front.
I know these are all different systems, but surely there's a simple way to connect the two together? I don't need audio, that already goes through an amp from the PC. I'd rather not spend a fortune on a converter box, as it's only to watch the occasional video on a larger screen, so is there a simple adaptor cable I can use?
Any home-entertainment boffins out there who can help?
Many thanks in advance!
