OK I have Nero and I cannot make a dvd. I go to DVD then make it so I have DVD video. I have avi and mpg files but all Nero will burn is vob, ifo, bup files. I cannot find any movie files that end in those and I cannot figure out how to convert files into one. How can I go about doing this? Do I need a program to convert it or where can I download a file like that? Or can Nero burn mpg and avi files but won't let me or is there a way so Nero will?
