Hardware :: New Imac-OSX 10.5.6 -how To Import From Sony Handycam

my problem is i cannot work out how to get video to imovie from my son's sony handycam DCR-HC28E. some say use a firewire but the one i have doesn't even plug into the camera let alone the computer!is there someone out there who may have this same situation and has resolved it? there are sooo many bits you can stick into your various devices for ICT[information and communication technology-for those who don't get that in their mail all the time!] that i find it very frustrating when you think you have what you want only to get home and find it does not work with yours, is not compatible and so forth.maybe someone might know a good online store which deals in all those things...connecting things to other things.
