Ok, so I bought a Wii finally. A few questions/comments on controls

[Ray007]

Congratulations on your Wii, and your (bigger than usual) initial game collection.

Regarding the jumpy controls or controller accuracy...

It is actually the remote that has the sensor not the bar.  The "sensor bar" only provides 2 distinct infrared (IR) sources - just a bunch of IR LEDs on the left and right of the bar.  The remote knows where it's pointing based on how it "sees" these 2 sources.

But, the remote will detect any IR source - including the sun, candles, incandescent lamps, maybe halogens (not sure) - so some things may throw it off.  This happened to me with an incandescent room lamp being reflected off a mirror - you'll notice this by seeing more than 2 points in the Wii calibration menu for sensor bar sensitivity. To fix the problem, get rid of the other sources (change lamps, close window blinds etc...) or turn down the sensitivity in the Wii menu so that other sources aren't detected.  I turned down the sensitivity, and controls have been great since (just need to sit slightly closer though).

But as someone mentioned before, you can use this to your advantage.  If you want, you can just use 2 big candles about 7" apart instead of the sensor bar - the remote won't know the difference and it (might) detect them better (I did this at my cousin's place when we forgot the bar).  But I don't like the candle thing... it can be a fire hazard .
