Where is the colours on my recording?

Hi

You have not given enough information see this post

In particular what settings did you use?

Did you use the composite input or the s-video input on the Grabby, and what is the video source and which outputs did you use?

This problem could be caused by using the S-Video port of the Grabby and connect it through an adapter(e.g. SCART) to an external device which is not equiped with a S-Video port.  If using a SCART plug on the video source do not use the s-video output - see image
