burning camcorder DVD to play everywhere

Hi

Hope someone can help. I am sure this must be the most newbie question asked.

I am hoping to burn a dvd I recorded on my HD camcorder to a DVD disc, that would play in the USA and UK etc.

So I think it needs to be region free? is that the same as NTSC and Pal compatible?

I will be burning using Nero and I am not sure if it just does this automatically fo rme?

Thanks for any help
