Ya know what ya do with those gigabytes of movies to optimize space???
get Winrar. And make a SFX (Self Extracting Executable) multi-volumed archives (650M Archives) for all your movies. Made Cd1, CD2, CD3...
So in the end, all you have to do is insert CD1, execute the single 650M executable, and start extracting from that one. Eventually it will ask for the disk with filename.r00, so you insert the second disk, press OK, and it will contiune to extract until all of them are extracted to the directory you want. You compress them down, and optimize the # of CD 's to burn them to
