I have noticed that on PC TNT explodes almost instantly, when grouped, but not on the Xbox version. Is the code different?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
Remember that the Xbox version is several versions behind; at launch, it was equivalent to version Beta 1.6, under which TNT behaved entirely differently (specifically, it could be set off without redstone). If you haven't patched your game (or are watching old videos), that could account for the difference.
