Canon camcorder?

I have canon MV930 and want to transfer video's from the TV/VCR on to my camera film but the book show this facility for the next model up not mine.
I now have a booklet easylifegroup.com which has a four core cable with Red Yellow White identicle plugs along with a black one which appears to look like a TV aerial plug. There is a gadget on the cable which I assume entraps the vidoe converting signal to that of the item connected too. Now this is a shot in the dark............Anybody used one of or similar attachments and have had sucess? As to pay £40 is a lot for something that might not work with my camcorder. MVI video recording.
Many thanks in anticipation.
