You've Posted Your Question To a TWO YEAR OLD Thread..
Please repost your question as a new topic on the main page of the forum. When you do so, please explain clear what you're trying to do.. You mix the terms CD and DVD incorrectly.. Are you actually trying to burn a DVD to a CD or are you trying to burn a DVD movie to a DVD-R disc?
Some other things to be considered though...
In addition, where did you get the "Step Up" movie? Since it sounds like a recently released copyrighted movie, did you download it from the internet? Attempt to copy it from a commmercial DVD?
If the movie is a copyrighted movie, our forum policies against piracy prevent us from helping you make illegal copies of such movies. In addition, if you have a recent version of Nero, it will eventually prevent you from making a copy of the commercially copyrighted DVD.
Hope this helps.
