IPhone 4 users how can I get the videos on my iPhone put on a DVD?

Any help would be nice thank you.

If you mean the camera recorded video, Connect your iPhone to computer through USB cable, and then open 'My computer', click on what should say 'Apple iPhone'(possibly have a picture of a camera next to it). And then go to folder 'Internal Storage -> DCIM -> 800AAAAA'. You should find all your pictures and videos that you recorded with your iPhone. After you copy the video to computer, you can use convertxtodvd or nero to burn the videos to DVD. Hope it helps. Contact me if you have any other question.
