It's interesting to note just how various setups will react with each other. I instantly got my sat and dvd hooked up via s-video switching in the 1050 and discovered that I was one of those who were doomed to have problems. Apparently my dvd player sends out signals outside the spec so I get flashes and picture rolls with dvd sometimes. They come in the same spot every time. Anyway, I guess I'd recommend trying your existing components out with the 1050's s-video switching just to see if you have any problems. I now have my dvd direct and composite for my sat (again...). Some good test material is immediately following the plane crash in Castaway, during the storm in the water, or the storm at the beginning of the Iron Giant. I would say if you can play through both of those with no problems, you should be safe.
Also worth noting, my experience with the Monster s-video is exactly opposite gonk's. Had a real cheap one and on a blind test my wife picked out the monster as well. I know not the best, but it's what I had available to me and it was better than generic brand.
