hi ive been recoding films to dvd format using avi2dvd using the guide on this website. the problem is that the files this software creates is fast using up my hdd space each conversion takes up about 9.4 gb. which files do i really need to keep after its done. i use image burn to write the discs so is it just the iso file i need. maybe ive answered the question myself if i have then someone reply just to tell me its right. thanks in advance.
