My sister had some DVDs of their vacation from years ago. They were originally VHS tapes transferred to DVD using a VHS to DVD recorder. When she tried to watch some of their own vacation videos recently, they would not play. The first thing that came to mind was that the DVDs were not finalized thus they would only work in the original recorder which they no longer have. My VHS to DVD recorder is also history.
I did some research online, and some suggested to use Nero to close it up. The only version of Nero I have is version 10 from 2010 on my Windows 7 desktop. So I put in one of the DVDs and opened up Nero. I couldn’t find the settings mentioned online, so I clicked around in Nero to see what I could find.
I opened up Nero Express and clicked on the button on the left-hand side that gave me some Advanced options. Then I clicked on Disc Info.
In the window that opened, I clicked on the DVD R options in the bottom left-hand corner. There was an option to Close VR disc.
It gave me a warning about not being able to add more data. I just clicked on OK.
A progress bar opened at the bottom of that window. It finished within a few minutes and the DVD then popped out. I took it out and put it into my other computer and then tried it on my DVD player. Sure enough, it worked.
Just a note: Both recorders where Toshiba.
