My mom works at an elementary school. She has a projector that she needs to hook up a vcr and dvd player. She'd really like a combo unit if possible. The problem is this: she says there are no composite jacks on the projector. She says there are component, S-Video, and VGA. All the combo units I've seen use only composite for the vcr. Are there any combo units that can pass the vcr signal through the s-video or component outputs? If not, what is the cheapest vcr that can be found with an S-Video output.
