Need to find a 3.3Mohm resistor

There's nothing wrong with getting a 5% tolerance. It will be better than a 10% one.

Sure, if your goal is to constrict a signal that much. But when you require that a signal that can vary as much as 10% either way (Over or under) it's not exactly a good idea.

The tolerance refers to the actual resistance. It's marked as 3.3M, but out of the factory it could be up to 10% higher or lower than the marked value. A 5% resistor is made to tighter tolerance and will be more accurate (and slightly more expensive). It has nothing to do with the use you put it to.

It absolutely does, otherwise there would be no purpose in tolerance levels.

When you're working with a video signal that can, and does fluctuate within those levels.......restricting the signal too much can cause a loss if it fluctuates outside the tolerance range.

Lowering the tolerance in a guitar amp by using a 5% instead of a 10% is a whole different story, it is more accurate and you're keeping the sound reproduction closer to what it should be.

Well you can believe that if you want. I'm not going to argue about a ten cent part any more. Good luck finding it.
