Burning HD camcorder footage to DVD?

I am currently thinking about purchasing an HD camcorder (possibly the Canon HF-10, HG10, or HG20). Now, I imagine transferring the file from the camcorder to my PC should be pretty simple, but what I am more concerned with is burning that file onto a DVD. (1) Should I have any trouble with that? (2) And more importantly, being that my footage is High Def quality, how would that be affected when burning on a normal DVD?

* I don't have a high def DVD player, but am currently looking for an upconversion one.
