Problemer med DVD-brænding

Hej. Jeg har købt en LiteOn DVDRW SOHW-1653s DVD-brænder (http://www.zitech.dk/product/details.aspx?sku=220527), og den læser cd'er og dvd'er helt fint, og den kan også brænde cd'er. Men når jeg (med Nero 6) prøver at brænde en dvd, får jeg fejlmeldingen "ulovlig disk" (jeg har prøvet med både dvd+r og dvd-r). Jeg kan heller ikke brænde med CDBurnerXP Pro 3. Nero giver følgende fejlmelding:
