"I've been told that WMM does not download from any camcorder" - don't believe everything you are told!
More infromation would help:-
What is the camcorder and how are you connecting to the pc (firewire/usb?)?
Are you correctly setting the camcorder controls for downloading to the pc and does Windows recognise it when it is plugged in?
Does WMM recognise the camcorder when it is plugged in to the PC? - What messages if any do you get when you try to d'load the footage?
