before I would get too bent out of shape on this video problem, I would use the RGB (three RCA cables, Pr, Pb, Y) connection for a better HD image on the screen than the Yellow only RCA connector.
You can use any set of three RCA cables... colors do not matter... just do the same color/connector on each end from SSL to Samsung... or go buy the correct color RGB three cables if you want. Just plug into the rear of the SSL to the corresponding outputs.
I downloaded a copy of your manual from here
Using either an RGB setup or using an HDMI cable setup will give you a better picture quality... you can still use the RCA Red/White audio cables, just add the RGB connection or an HDMI connector that combines video and audio in one connector.
