i quite new to burning...i have nero sure start which i use to burn music etc,but it doesnt seem to burn av1 movies to dvd..it tells me i need nero 6 ultra etc.
what i need to know is which nero shall i use and which is the easiest to use and install...any links to free downloads would be appreciated..regards

 

DVD Flick will convert avi to dvd format and optionally burn the disk.
It includes a clear, concise guide.
Its burning program is superior to Neros.
