If it's a single RCA jack, it's "composite" not "component" video.
Composite video is NTSC format, which puts the luminance (b&w) and chrominance (color) on the same wire. The two signals overlap, and can never be perfectly separated. The chrominance ends up bleeding into the luminance, and vice versa. Higher-end equipment tries hard to do a good job of this with fancy comb filters, etc., but its difficult to do.
In S-video the chrominance and luminance signals are carried on separate wires, so the TV doesn't have to do the hard job of separating them. WIth analog cable this would yield no improvement, since all the channels are transmitted on the cable in NTSC format anyway, and the STB would probably have a very cheap color/luminance separator. But on digital cable, at least some sources, at least some of the time, may not have ever been in NTSC format, and you may notice a difference with the S-video output. However, on many of the DBS channels I see, NTSC artifacts are noticable, indicating that they started out in NTSC. It'll probably be hit or miss as to whether you see an improvement.

Can any of you engineering einsteins help me?
As I wait for a decent STB before getting satellite, I am stuck with
"Digital" cable. The latest box I got (today-Motorolola 4000) did in fact have a digital dolby ac-3 out which makes the system sound noticeable better when viewing digital channels.
My question is: Will I do better getting a S-video cable and using that to rout the video out of the cable box, or is the single RCA-
type video out component connection usually better?
Thanks in advance !!
