Nero video resolution problem

i tried burning some video files to a dvd using nero 8. but the screen size is too small. its the same as the input video size, i.e. 320X240. how do i make it bigger using nero vision or other nero tools?

If you want larger picture size, you need to re-encode the video. But doing so will most likely result in grainy crappy looking video…

There would be no benefit to reencoding to a larger resolution. In fact, it will likely make it worse. Each time a video is encoded reduces quality.
