Hi
Do all VOB files fail to load?
Can you upload one that fails to GoogleDrive or Dropbox where we could check it? You may send the link via private message.
I assume the VOB files are not from a copy protected DVD as they're family videos.
I've tried the latest version with VOB files copied from my own home DVDs and they get imported successfully.
Please check your inbox too. I sent the link for the older version that you can try.
Thanks
