If you’re having problems with the cursor bouncing around, go into the Wii menu and bring up the sensitivity screen. It will show the output of what the IR receiver is picking up. You should only have two dots. If you have reflective surfaces around the receiver it may be picking up some reflections. I had a problem with a mirror on the wall near the TV. Once I fixed those issues, the cursor is totally solid.
Let’s keep it on topic, please.
Advice duly noted, but none of the Wii’s I’ve ever played on was -mine-, so I don’t know that I’ll get a chance to fine tune. 
Then it’s either your hand, or all three had weird lighting conditions. I used to work customer service at Nintendo and have used dozens of Wiis–none exhibited these symptoms except when there was some kind of light interference (or if you’re too far from the TV–say 10-15ft). As someone else noted, glass services can reflect light as well that can interfere–adjusting the sensitivity usually fixes this.
Again, that’s abnormal. I’m not doubting what you experienced, but merely pointing how that’s not how a Wii should behave. And seriously, comparing it to the EyeToy? That’s cold.
Well, considering that all three were in rooms I’d consider to have ‘normal’ lighting conditions (windows present, but no sunshine directly on anything) and the ‘twitch’ didn’t appear to be limited to my controller, I can only presume they were poorly tuned.
I had a very similar problem. The little targeting reticle would shake like crazy for no apparent reason. We solved it by removing the Christmas tree from the living room. Somehow or another, the ornaments on the tree were interfering with the reception from halfway across the room!
The infra-red light emitted by the lights was likely bouncing off your TV’s glass screen, thereby being picked up by the camera in the Wiimote. Adjusting the sensitivity may have fixed that, but you found a method that worked too 
Have you looked at the Active Life Outdoor Challenge? It has a floor pad that is used to track leg/foot movements. I enjoy it quite a bit.
Random stream of nintendo rants
I own a Wii, and I waited overnight back in Dec. 06 for mine. I have 14 or so games.
Nintendo needs to ge their head in the game on Internet and frankly, GUI. And yes the shovelware can stop. Apparently Big N isnt going to touch M games too much. Fine. If Wii can’t get a Deathmatch game, can we at least have Mario V. Sonic Capture The Flag? Oh wait, in order to do that, we would have to revamp “”“Friend Codes”"" wouldn’t we?
There is no reason why Nitendo can’t do all of the same things that the Xbox 360 GUI does, right? (I’m not saying it can pull off the same games that the 360 can. I am just talking about navigation of the home screen(s).)
Why do we have the cumbersome “Channels” for Wii, when Xbox has “Blades” ?
And it’s not like the 360 is newer than the Wii. (Because it isn’t)
I’m Fed up with how Artifically. ARTIFICALLY slow the Wii is. To say nothing about the other Multimedia content the Wii can be doing, but doesn’t do. The Wii is going to get streaming Netflix, right?
Yeah, and I just got an Ipod Touch. The Nintendo DSI doesnt appeal to me at all. --If It could get online by itself, outside of a hot spot, then maybe.
The Conduit is M with online deathmatch. Due next month, I think.
Nintendo has published two Mature-rated games in their (both for the GameCube): Geist and Eternal Darkness. So bitching at Nintendo for not publishing Mature-rated games is missing the point just a bit.
And Cisco, The Conduit is due in June.
I’ve loved my Wii so far, but it’s honestly only because of Resident Evil 4 (which I understand was a Gamecube game first). Right now I’m in the market for a great, epic RPG like one of the Final Fantasy’s. I was really disappointed by the Zelda game I got, though. Liked it even less than Majorah’s Mask.
Good news, Final Fantasy IV: The After Years was just revealed for the Wii by the ESRB.
That’s neat, because I liked FFIV, but it’s too bad it’s just a port over of a 2D cell phone game.
D’oh. Did they push it back? I thought for sure it was March or April.
It was set for a very vague “Spring” release date. But Nintendo just put out their Spring/Summer calendar yesterday and The Conduit was penciled in for June. I think it was more a case of a game that didn’t really have an official release date finally getting an official date than a delay.
Only having two titles in their history (both released for the previous system, mind you) is exactly proving the point. Two outliers don’t make a strong case.
Huh? What sense does complaining about Nintendo failing to make Mature-rated games make?
They don’t make Mature games normally. Yelling “They’re still not making Mature games!” doesn’t hit on some universal truth about the Wii.
Why does a game have to be rated as “Mature” in order to be mature?
Ask the ESRB.
Justin Bailey: You’re barking up the wrong tree. I don’t care if they’re Mature games or not. I just want them to be good. I was just pointing out that some people use that as a criticism of Nintendo and if you care about that, it sticks.
