Iso burning problems

hi i was wondering if anybody on here could help me. i have loads of avi video files on my computer, that i wish to send to disk. there is only one way i can send them to disk, and that is by converting them to dvd format first. i have already converted two video files, they are in seprate folders. the problem i have is that when i go to use my burning program “Nti cd and dvd maker 7”, to burn the files to disc. it says that there is already a file called that in the dvd burn list, i also need the files to be in order. so i don’t have bits of the first video file poping up in the second one. i would be greatful if someone could help. thanks

I think your conversion went wrong then. Try ConvertXToDVD.

thanks i will do

is there any free software that might do this
