In your first post you said the TV only has RCA connectors, which to me would mean Composite.

Since you say you have S-Video on the TV, how many connections? If only one then you have to determine either which you watch more TV or Dish and connect one via S Video to the TV(assuming one S connection) . . . or if only 1 S-video connection then I would connect both the Dish and DVD to the 1050 via S-Video and use the 1050 as your A/V Switcher.

Make sense?
