I've plugged my Wii on a HDTV!

Lag is a combination of your TVs responce time and the cables. You MUST use component cables, the colors and details are superior, but the most important thing is the lag. I have my Wii connected to a 26" HDTV with 8 ms responce time, useing compsoite cables, the lag was horrible. Useing component cables, it was just like my old CTR tv,

Would such a thing happen with older systems that don't have component options?

I would say so. Useing compsite cables (or anything 'worse' than it) on an HDTV creates lag. Your TV has to process the analog signal into digital, adding to your TVs responce time.
