I'm currently getting a movie off Limewire. I'ma burn it 2 a disc. But idk if my

computer has a dvd burner.... It is a Dell. On the tower, it has TWO cd thingys, i dunno if one of them is a DVD burner or not... I tried to put a DVD in one of them, but nothing happend. even if it doesnt have a dvd burner, can a movie still burn onto a dvd/ disc???????
Thanks
