I've just bought a Kodak zx1 HD camcorder, and I'm very impressed with the quality of the footage when played back directly from the camcorder on the TV via the HDMI cable. (The TV is about three years old, not state-of-the-art but HD ready). So far, so good! 
However, I want to make copies of the footage for a couple of family members who don't have HD ready TVs. I've tried burning a DVD on the PC (using Roxio Creator 2010), but it comes out very jerky, and the sound doesn't work. Do I need to change something in the Roxio settings? Or doesn't HD footage work on anything non-HD?...in which case should I be using the VGA setting instead? It seems a shame to sacrifice the brilliant HD quality altogether, just because *some* of the intended recipient DVD players are non-HD.
Or is it the fps setting that's causing the jerkiness? I've been using the 60fps setting so far (as I assumed this would give me the best quality) but would I be better off with 30 fps? What are the advantages of one over the other?
Huge thanks in advance for any advice.
