A full movie is normally around 700 Mb or more. Not sure about saving to a dvd, but I don't think so. LW requires the saved folder and incomplete folder to be in the same location. There are are programs out there that will let you copy the file after it is downloaded. You could do a search for them. As for codecs you can do a search here (upper right) for codecs. You will find some threads with links to some sites that have them or a player which has them built in.
