I have had six computers in my life. All of them were either not worth fixing, broken or hanging by a thread. Recently I got an emachines 1161-07. Problems solved. NOT... Now I have to burn a DVD on my new system and I cannot burn all the great shows I have on my computer to DVD disks. The authentication process has some kind of error where it says something like this (cannot use avi format files to burn the disk - must authenticate through Nero). I am using Nero to burn video and it will not allow me to burn these shows becuase they are not the original disks. They I tried a DVD ISO burn on Nero and it worked, but my friends DVD player will not read the ISO format. What should I do?
