Img burn buffer complete but won't complete the rest

[JObloggs]

I am using dvd flick to burn a small video, only 5 minutes long. I expect it to take a couple of minutes to burn as I've used Img burn before. The Buffer goes smoothly but the remaining device buffer and completion hasn't started after 26 minutes. Can anybody fix this urgently please?
