cheers. the fish eye effect is due to the wide angle of view these GoPro cameras have. you have to frame shots by gut feeling or take a photo and then chuck the card in a camera so you can check framing, but as that takes too long most times i just wing it and hope for the best, lol.
as for the editing software, i'll continue on with imovie for now. its capable of some cool things, at a cost of plenty of hours work, lol.
