Thanks, this is all sounding like a bit more than I intended - I didn't realise the PAL encoding was between component and S-Video. It is looking like splitting the component video is going to be a lot more straightforward.
My other option is tracing the pin connections are on the video card - it uses a 7 pin mini DIN connector and comes with a breakout cable for component and an S-Video to composite adapter, which would indicate all signals are present. If so (they could be on the three 'middle' pins) I'll look at just building a breakout cable if I can find a suitable 7 pin mini DIN plug.
Thanks for your help.
One other thought - in standard VHS VCRs are the Y and C signals ever separate at any stage? Just had a thought about capturing old VHS tapes with better quality...(sorry, drifting off topic)
