I think the video is spot on. There are two types of lag one is when the game slows down due to interent quality issues, and frame rate lag, which is because of the Wii's low ram capabilites.

But still, I guess lag is just a universal term for when the game slows down, but any who, there are two different meanings for it.

Your ignorance to realize that is ignorant. Lag is lag. No one cares, like what codcanuck said; if  the game is slow, then just call it lag. No need to get technical

I don't like it when someone of "authority" calls someone ignorant. You're a forum mod, it is your opinion, not all of ours.
