Error occurs when burning DVD on Windows DVD Maker?

Question by : Error occurs when burning DVD on Windows DVD Maker?
I have a windows vista laptop with the Windows DVD Maker program. I’ve tried numerous times to burn a video (19 minutes on .wmv format) and an error keeps occurring. I’ve changed the speed and the temporary file location but nothing. It gets to “Encoding 6.1 %” then it jumps to “Encoding 71.8″ and then it jumps to 98 % and the disc comes out but I get a message that says “An error occurred when burning the DVD” Any ideas?
(I’m using a DVD+R disc)
