I am a two-day old Wii user, so I certainly don't know all there is to know about sensor bars and remote sensitivity, but I have done extensive searching all day on various forums and sites about this, and haven't found what I am specifically looking for, so I'll take a chance and post on here. I have also posted this in the SMG forum here, but I think it's relevant enough for this forum as well.
My cursor jerks and is really twitchy on Super Mario Galaxy. When I move the cursor around the screen (to pick up star bits, for example) the cursor jerks around and the wii remote rumble activates, like I moved the cursor over a button or something else selectable. Of course, nothing is there to select, so it just does it randomly. Also, it makes it really hard to select anything - when I put the cursor over a galaxy or a level within that galaxy to select it, the cursor freaks out. I can still select the selectable item but the icon freaks out, the remote rumbles almost constantly, like I am constantly moving my remote from and back to the selectable area (sorry if this is confusing, it's really hard to explain). Incidentally, I have tried this with two remotes, both with fresh batteries, to the same effect.
I also get this a little bit with the Wii menu, but it really goes into overdrive with Mario Galaxy. I have also tried Wii Sports and Trauma Center: SO, and it's not nearly as bad as it is with Mario.
This sounds to me like a sensor bar issue, but I have no other lights or IR sources (except for my cable box about 9 inches above the TV) near the Wii or the sensor bar. The only thing I can think of is that I have two glossy 24x36 posters on the wall behind me, but not directly behind me, about 6 feet either side of me - can these reflective surfaces also be the culprit? I also sit about 6 feet away from the TV as well (it's a 32-inch CRT). The sensor bar is on top of the TV, at a slight downward angle, but I've also put it on the bottom of the TV (and changed the Wii sensor bar options accordingly) and the jerkiness doesn't go away. I have used all 5 remote sensitivity settings, and it seems to work the best at the '5' setting, but it doesn't completely get rid of the random jerkiness/rumble.
Like I stated, I just got the Wii a couple of days ago, so I am most certainly a Wii noob, but I think I have done everything correctly in terms of setting up the Wii and sensor bar.
Has anyone else experienced this - I can still play the game fine, just the jerkiness of the cursor is really bothering me.
Any help would be GREATLY appreciated! Thank you!
