Can I "delete" or "erase" a half filled DVD-R, in order to add another movie in DVD Video format?
I vaguely remember that erasing was possible, but of course it was NOT really erased, it was simply made unreadable, but the remaining, empty part was still available for writing.
I have already added the movie in Avi format, so i know there's some sort of multi-session possible when I write in ISO format, but it won't show up in my stand-alone DVD player, it just plays/shows the old bad version in DVD format.
I have this DVD in DVD-Video format (with the Video_TS and Audio_TS folders), which contains one bad quality copy of my birthday party's home video, the audio is out-of-sync. I now have made a new version of this, audio is now in-sync!
So, I don't care anymore what is on the DVD-R now, I just wanna either add my new movie to it, or replace the old with the new one.
I guess I theoretically have those 2 options:
1. "erase" the DVD-R, that is, make what's already on it, unreadable, which would leave me with a DVD-R with about half the capacity.
2. "Add" the new files to it, which would give me a DVD-R with two movies on it, the old one and the new one.
I don't care either way, I just wanna know if its possible, and what tools I should use.
And yes, I'm aware that I could buy a new disc, but for various reasons (lack of time, we're effing snowed in), just going to the store is not really possible ....
