Problem with DVD XCOPY XPRESS!!!! HELP!!!

Ok, I installed the program, and inserted the movie. After the program read the disk it said to put in a blank DVD. I did this, and the button that says "START" never becomes activated. I don't know whats going wrong. I read somewhere that you could download new media or something to solve this problem??? I dont know. Please help! How can I get it to recognize the blank DVD?
P.S. - I have tried both DVD-R and DVD+R formats, to no avail.
