miniDV tape based camcorders. DV (or HDV) transfers from camcorder's DV port over firewire to the computer's firewire port. DV can be used by pretty much all video editors directly, including MovieMaker - and *most* of them (not MovieMaker, though) can do HDV.

DV is DV no matter which manufacturer - same with HDV... all manufacturers do it the same.

This assumes your computer has - or you will add - a firewire 400 port. Firewire 400, IEEE1394a, DV and i.LINK are all the same thing.
