Can video be progressively scanned twice. If it comes out of a progressive scan player then through a video converter that also does progressive scan, does it get scanned twice ? Or am I way out ? Can you get poor quality progressive scanning capabilies. If I get a cable that starts with component and put an adapter on that goes from three phono's to svga will my projector recognise it as svga input. Also does vice versa work, an svga adapter to three phono's, will my projector recognise it as component. Thanks.
