abel46, the reason that you saw the difference is that DVD is Standard Definition. So for Norway, you would be going from a 1920 by 1080p image to a 720 by 576i/p image.

However, from what I’ve found, even when shooting in HD, if you are going to show the video anywhere without a computer, it is better to have a DVD, as more places will have DVD players, rather than Blu-ray players, connected to TV’s or screens, and even if the place does have a Blu-ray player, it will still play a DVD.
