I'm confused about the importance or usefulness of ..."component video upconversion" If the video source is an S-VHS VCR or a Satelite TV receiver with S-Video output, will the component video upconversion actually IMPROVE the signal by converting it from the 2-channel S-Video signal to a 3-channel Component Video signal? Or does it merely act as an "adapter" that allows you to connect your S-Video equipment to a component video input device such as a video projector? I'm confused. Please help!!!
