it does have scart so I was thinking of scart to svideo + audio as the tv does not have scart but it has svideo input

Either way I'm already in the process of returning the hdmi to vga cable as its not working
Scart is a type of connector, it's not a type of video format.
The scart output on the Tivo can output RGB or Composite video, it does not AFAIK output S-Video.
If your Tv has composite video and audio inputs, coloured yellow, red and white (or black) then a scart to 3 phono lead will work.
The picture quality won't be up to much but you'll get a picture.
You could have asked on here before buying the cable, we'd have told you it wouldn't work.
HDMI is digital and VGA is analogue, to convert from digital to analogue requires a black box convertor, a simple lead can't do it as you've discovered.
