What you're seeing is the result of two issues:
1) You're taking (I assume) a standard definition cable signal at 720 x 480 and pumping it out to a monitor that is natively 1920 x 1200. That means it has to scale the image upward, exactly like Windows Media Player does. Sometimes this looks "ok" (a DVD for instance), but over S-Video and relying only on the scaler in the monitor...not so much, as you're seeing. There's really nothing you can do about this.
2) S-Video is a poor way to transmit signals. Does your TIVO unit have component (red, blue, green)? Try that instead.
