The DVD burn wont matter as much as what format they are in. Nero can do some DVD coding but not all. If you downloaded a PAL format and you are in the States they wont work on all DVD players. Gotta make sure you have the right region coding.
Are you just looking to code .avi files to movies or to burn ISO's?
