RF is generally inferior because the signal must go through two tuners: the tuner in the cable box converts the signal to channel 3 or 4, then the tuner in the TV converts this signal to video. S-video involves just a single conversion inside the cable box. Before swapping out for an S-video box, try a good quality composite cable. I like Tara Labs, but there are many others.
Digital cable set top box connections
A guy I work with just had digital cable installed and although the T.V. has component and S-video connections the cable guy installed it with the digital RF cable from the wall into the box and another RF cable from the box to the T.V. The box doesn't even have S-video or component outputs, only an RF and a single composite. The question I have is this; since the signal out of the wall is digital is the output RF also digital? If so is this the best possible connection? The cable company does offer a box with an S-video output but would this be a better connection? I've always known that S-video and component are much better than RF but is this true with digital also? Should he get the S-video box? Thanks in advance for your help.
