Lol I meant nero vision only :o …this bug is really makin me go nuts 
Yeah i also thought it was serial number issue…but other Nero progs like the burning rom, recode, etc are allowing me to make DVDs and even Smartstart shows an option to make video DVDs but just when I click on it Nero Vision appears with no option for DVD…so I was wondering if it is really a serial no issue ??
EDIT: Okay, I’ve tried several serial numbers now, incl for Premium Ed., and a Ultra Ed. serial no. from a comp on which Nero Vision shows make DVD option…so I really don’t think its a serial no issue…
