I'm going to purchase that SCART->SVHS cable today and see what happens.
I've realised I can also use this cable to attach my TV to my ProGrab 24RT Plus framegrabber which I aquired a few months ago off eBay but never used. This accepts both composite and SVHS cables from the TV but what about the signal from the TV to the ProGrab box? The signal being sent from the TV must be RGB so will the ProGrab box convert the signal into SVHS? Surely it must do.
Well I'm pretty much resigned to the fact that my TV won't accept the signal sent from my GeForce 3 card (hope I'm wrong) so hopefully the cable will work ok with ProGrab.
