Due to the myriad of questions I have, I think it is best to list them in numerical order for your convenience. 1. My Nintendo Wii becomes excessively jittery and jumps all over the screen at 8 feet and the cursor disappears at 11 feet. There are no interferences such as infrared radiation in the room that I am using the Nintendo Wii. Is this behavior normal? 2. I am using a CRT big-screen television. I have heard on this forum that big-screen televisions may reduce the effective range of the Nintendo Wii's sensor bar. Can you confirm the validity of this statement? 3. Based on the information above, do you believe my two Nintendo Wii remotes or my sensor bar are faulty? 4. If you believe I possess faulty hardware, what course of action should I take? 5. Are there third-party sensor bars that are more effective than the one that came with the Nintendo Wii? 6. What do you know about the effectiveness and process of constructing your own sensor bar? 7. In another thread entitled "How far can you Wii?" on this forum someone mentioned "high-powering a Wii" that would increase its range too "100 ft. or so". Is this true? 8. Which is the most effective sensor bar: a third-party sensor bar, a self-constructed sensor bar, a "high powered Wii", or a combination of the above? I greatly appreciate your responses in advance.
