help on burning copyrighted DVDs

I'm having computer problems right now. It is taking so long to download some files and it seems like it's crawling. I cannot determine what could have possibly gone wrong. The last time I did was I was trying to burn a copy protected DVD. I was looking forward to see the video of a movie. I was looking for some online help and stumbled into an article. It says in how to burn copy protected DVDs that it really takes so much of your hard disk space. What can I possibly do about it? Should I buy larger hard disk space, or partioning it will do good too?
