It sounds like there are at least two different issues being discussed here.
Overshoot
The "ringing" or "ghosting" you'll see to the right of sharp edges on static (or moving) images is most likely caused by overshoot, which I believe is an issue inherent to the analog electronics of cathode ray tubes. (Though it's certainly possible that feedthru/cabling/shielding/power/etc. issues could contribute to the problem as well.) If your game has an anti-aliasing option, make sure that's turned on, because it's the razor sharp (primarily vertical) edges on game graphics with no anti-aliasing that will make this issue most apparent.
There may be some things you can do to fine tune edge-filtering to diminish this a bit in the SM. But it's unlikely you'll be able to eliminate it completely from sharp edges with no AA at all. Turning VM off may or may not help as well. Lowering Sharpness should help, but that will of course mean sacrificing some detail/clarity in the image as well. This is one of the tradeoffs you get with CRTs, which really weren't designed with the such sharp graphics in mind.
Overshoot can look similar to
edge-enhancement btw, but these are really two separate issues. Edge-enhancement is an effect applied in the video source to bump-up detail, while overshoot may originate in the mechanics of the CRT itself.
Overshoot is also different than over
scan (which is a completely different topic).
Phosphor lag/persistence
If you see an "after image" or "trails" following bright images or moving highlights on the screen, that's caused by phosphor lag/persistence. Not all phosphors are created equal. Some kinds of phosphors (such as the type you would find on high-refresh PC monitors) fade to black faster than others. Sony seems to use relatively slower-fading, higher-persistence phosphors on many of it's TVs to help boost their brightness, which is why I don't generally recommend them for gaming.
There is some "circumstantial evidence" to suggest that this issue might diminish a bit as the TV breaks-in. It's hard to know if it's the phosphors themselves changing though, or simply viewers getting more accustomed to the effect. If there is any actual reduction though, it certainly won't eliminate the problem because of the type of phosphors that are probably involved. The effect will be most noticeable however when viewing in total darkness, so your best defense against it is simply to turn a couple lights on in the room (which is probably better for your eyes anyway). Adjusting gamma on the games or DVD player may help some as well.

Using a different cable or input might possibly have an effect on the overshoot, since the edge-filtering in the TV differs a bit depending on the type of signal. But probably will not have any effect on the phosphor lag, which seems to be your main concern.
FWIW, DVI probably exacerbates the overshoot a bit on my 34XBR800, because the signal is so clear and razor-sharp. YMMV.
