WOW, you could have never explained the difference between OTA vs Direct TV. I has estatic moving from comcast to Direct, and this is another leap in quality, both video and audio. Was a little concerned with doing this, pppffffttttttt Two issues, for some reason my S-Video cable removed from the D*Tivo and put on the S3 isn't transmitting the video. It worked immediately before the transfer. Do I need to set something on the S3 to tell it to use the SV? Channel search picked up a bunch of channels that I can't actually receive. How do I remove these from the lists. The screen instructions indicate I need to push the clear button, but the system would accept that input.
