still not clear on what your trying to do
are you trying to copy outher dvd's?
there is better free options for that purpose than ulead movie factory but heres how
first use
dvd decrypter to decrypt and save dvd files to the hard drive
then you can use ulead movie factory to downsample the files and edit them but theres beter options to do this so you dont lose all the menus and stuff what ulead movie factory is relly good for is converting/ burning mpg 's,avi's and stuff like that to DVD's
