Well obviously you can put g68 in standby and try it yourself with a composite signal or whatever you have available.

However iirc that 562 video would remain active in standby and I think this useful feature was carried on into g68. Not sure if it would transcode formats though ie s-video/composite but I don't think component will need any passive components for just switching.
