Question about hookup

Hooking up the 950 using S-video until I order a longer component cable. Can't get video.

I have the dvd s-video out to the 950. The monitor out from the 950 to the television. Also, using video-1 for cable set top box and it works, but no video from DVD player. What am I doing wrong??? Can't the 950 be used for all of the switching.

Thanks, bp
