Burn Video into DVD, and the Video becomes burry

i use Nero to burn some downloaded video into DVD, and the image become so blurry( it was in good quaility when i watch the video in my computer.)
i wonder what is wrong, and how can i fix it?

Hi rianna

If the video was an original then there should be no loss of quality when burning it to a DVD. (apart from compression etc etc etc.)

If it wasn’t an original then I can’t help u here because I don’t know anything about it… (chuckle chuckle)
