To save you from trouble of testing out the various IR LEDs, you may want to just use the Vishay TSAL 6400 with the wavelength of 940nm.

For the issue of the the previous post, it may be due to the IR LED having a not optimum wavelength or low powered. Also, it may also be caused by a faulty/non-genuine Wiimote.
