there are no receivers right now that will convert s video or composite to component. you can however buy and Iscan line doubler. this will convert anything you throw at it to 480p. you can pick them up for around $450. ther is an I scan pro for $650 that will take component inputs so you could run you component out from you dvd to the iscan but I don't know if it would be worth the extra money. basically it might make you cable viewing better and solve you switching problem at the same time.
