How can I extract unfinalized videos from a mini DVD created with a Sony Handycam?

I have a Sony Handycam, it also captures some videos and I saved one to a miniDVD, but forgot to finalize it (setting in Sony Handycam). Unfortunately, now I don’t have a Sony Handycam.

When I play this DVD in my PC it shows “Empty” but in “Nero” it shows size about 1.3 GB. So, I think my videos are alive on the DVD, but I am unable to read/see them.

Please someone tell me how can watch this DVD?
How can burn it to another DVD?
How can I finalize a Sony Handycam without a Sony Handycam?

Please help me!

Thanks in advance!

    - Save the C code as: dvchop.c

    - Put the dvchop program binary where it can be conveniently executed.

    - Use dvdisaster or readcd to perform the unfinalized DVD recovery
      (note that an unfinalized DVD is not mountable)
    - Use dvchop to extract .vob Titles
    - Pick the .vob files you want to keep.

    The purposes of this program are to:
    - produce clean .vob files for editing recorded video.
    - extract contiguous VOB sectors from an .iso copy of an unfinalized DVD.
    - recover DVD video without re-encoding, decoding or muxing.
      (note that the produced output files may be rejoined to reproduce
       the original input file)

    Extra:
    If you want to make One title from several, use the following type of command:
    cat movie_002.vob movie_005.vob | ffmpeg -i /dev/stdin -target dvd -vcodec copy -acodec copy test.vob

    I have a similar problem. I have finalized the video from Sony Handycam. There is mark in the disk which indicates the data. I can play that video back in the Handycam itself but when I put into the computer the disk is empty. If there would have been a file of any format visible, I could have extracted.  How can I make this work?

    One way to do it is to extract the data to a .tao file using the free version of ISOBuster (expanding on what souheil1337 said), and convert that to a format your computer can play. You might want to split it into individual programs, so I'd demultiplex, edit and re-multiplex. I'd then use VOBEdit to demultiplex, though MPEG StreamClip might also work.

    OR

    Try to copy the unfinalized DVD using Alcohol 120%/copy wizard/copy-on-the-fly. The copy made using Alcohol 120% should play perfectly on your computer or other device.

    Hope my research has helped!

    If the above comment worked you may also use VLC to transcode the video into another READABLE format. Of which you can then convert back to DVD and put on a regular DVD if you so choose.

    I'll do more research, but thats I'll I have for now.

    You may try Isobuster,
    This program will read the dvd's content and show that in the explorer, you can copy the content to your desktop and watch the dvd using VLC player (the player is able to play damaged files.)
