S-Video problem.

Hi. I use SuSE 9.1 Proff. here, and have a Nvidia card in the computer. I have tested with a video-dvd in the dvd drive, but cannot get any pictures on the tv in the diningroom. The film is shown ok here in Kaffeine. I have an s-video cable from the connector at the videocard, and an audio cable from the audio card in the computer into the diningroom. Here I have put the s-video connector to the s-videoconnector on the SCART-Connector. Also I have connected the audiocable to this connector. I have audio on the tv, but no video. What do I lack, and what position should the tv be set in ?. Erik Jakobsen.
