I don't know where you are, but the difference in picture when I hooked up the s-video out of the digital cable box makes it worth it for me. I don't know about the DSS. I have cable internet so I stick with the cable TV.

The 600 MHz has nothing to do with speed of data as it does in clock freq of computers. It has to do with the center freq of the band that the data is xmited on.
