The firewire card(mac term) is also called a 1394 in pc.

I once tried MovieMaker long ago, and lost some great footage because the maximum save/transfer resolution was 480x?(while ago). Then I got Pinnacle's Studio v.7 and am pretty satisfied, but some of the format transfer(i.e. QT -> Divx) isn't available.
A word of caution- I just tried to burn some stuff(web pages, pics, videos) saved from the internet using MuVee's burning function, and a WHOLE lot of "failed to work, Digital Rights Mamagement infringment" warnings popped up on some really common, public stuff.
Really annoying.
Also save as .mpeg, so the movies can be played on "other than MS" players (their EULA alows them them to scan your computer for media files-scary)
