I can't comment given so few details. I will share that I use other tools like CDBURNERXP to record files on DVD media every other day without issue. But some might use a Nero video dvd maker which has to encode the video or build menus and there can be transcoding issues. I can't help except to identify that issue but look at your post. How can you tell from the details presented?
I am trying to burn a specific set of videos onto DVDs becuase they take up 30gb. Every time I try to burn them I get an error. After failing to burn them a dosen or so times I tried to burn a different kind of project and my DVD burner no longer functioned.
So I bought a new DVD burner and burned several discs with the same media. Never had an error. I went to burnt that old project and came up with an error. I have become paranoid that if I try to burn the old project, my new dvd burner will fail.
