Connectivity between HTPC and STB

[machinist]

I know that I need a SCART to S-VIDEO with 3.5mm stereo jack, but the only one I've found so far is this :
http://www.profigold.co.uk/products/pgv670.html

However, it states in the description :
"Please note that this cable will only work properly in the one direction (PC into TV). It is not suitable for capturing external sources into your PC or Laptop."

This would then mean it would be unsuitable for pushing the picture from my STB to my HTPC ???
Any help/suggestions really appreciated.

Thanks
