Dvd

Hello,
I have some games I would like to burn to my dvd-r disc.I have a dell inspiron 1525 laptop with vista and it runs pretty fast.My problem is is that every time i put my dvd-r 4.7gb into my laptop nothing happens. It makes noises and thats it.I go to computer and click on the drive and it ask me to format,them a message pops up saying windows was unable to format drive, does anyone know whats up or how can i download another drive from the internet that can read 4gb dvd-r disc.


Thanks in advice.
