video files I wanted to share but can't...suggestions?

Hey, just got to Portland, Oregon yesterday....what a nice, cool city! lots of bikes (compared to other cities in the US), many young people, good coffeehouses with great caffe latte (I will never drink 'koffie verkeerd' in the Netherlands again), nice, unexpensive (!) hotel in a good neighbourhood ('Washington Park Inn')...
I would love to share some videofiles with you, but I got a problem...so if anybody is really into video...help is appreciated. I have a digital camcorder with harddisk which should be compatible with my macbook (imovie)..at least, that's what the guy at 'It's' in Rotterdam said...unfortunately my macbook doesn't like the .mod / .moi -files and I cannot import anything.
Checked lots of forums on the internet but everything sounds pretty complicated or costs money...

So...what's the secret???
