Millreef: Hi, Did you ever get an answer to why you "cannot coppy <file>. The Parameter is incorrect" ?? I am having the same problem. I've seen some advice out there, but obviously from people who haven't experienced what you and I are getting.
I have a JVC Everio MG-20HD Camcorder.When i try to transfer Video from Camera to PC it starts to download then after about 30 seconds it stops and the following message pops up.(Cannot Copy MOVO4A.The Parameter is Incorrect.)This pops up every time i try to download to my Desktop PC.It downloads to my Laptop okay and to my two friends Desktops,but not to mine.Running XP Home.Thanks for any help.Millreef
