What you're going to have to do is break the file up into segments, and burn the segments to discs. Then you'll have to get up and change discs every so often.
Okay, so i bought a cheap external dvd writer/burner off Ebay for my Sony Vaio laptop. I have a .avi file that is 69 GB, which i know is very large. I think there is no such disc that will fit all of it on one, but where do i start? What items should i buy to complete this task? What program should i use? I am new at this but promised my mom i would do this for her, so i want it to turn out good. I want to be able to watch the files on the dvd player on the tv. Any help is greatly appreciated!
