You'll need to rip the DVD using some DVD ripping software... There are quite a few available online (just search Google). Then you can just drag and drop the files to the flash drive. For the sake of organization I like to rip and convert to .AVI or another video format so that way it's just one file. If it were a data disk you would need to make it into a disk image (eg .ISO) but it doesn't sound like that's what you are trying to do.

answer is no if the movie already in the cd. you have take it out first. it have to use programs.

No you can easily copy dear just try formating the flash drive in NTFS Format

rip the cd first to your computer using something like windows media player, then copy the files to your flash
