I got a Series II for christmas and currently have it hooked up through a RF cable. As a result the video quality is horriable. I want to connect it through either composite or S-video to improve quality (which would you reccomend?) And I also have the problem that the Tivo is 30ft away from the TV. Should I invest in good quality shield cables because of this length and possible interference or are cheap cables good enough. What about these "Rapid Run" Cables. Any suggestion to improve my video quality?
