Q: I have a library of old DVD Camcorder files from years ago. They are all in .vob format. Windows 7 would play them absolutely fine. However, I've upgraded to Windows 10/11 and now it won’t play them at all. Is there a fix to this problem?
A: VOB is the container format that is typically stored in the VIDEO_TS directory at the root of a DVD. It's very similar to MPG format that can contain MPEG-1 or MPEG-2 video. However, Windows 10/11 does not natively support DVD playback. Windows 10/11 can play MPEG-1 video. If you want to play MPEG-2-encoded VOB files on Windows 10/11, you may get error messages.
This is also the reason why Windows 10/11 won’t play MPG videos. After we understand the crux of the issue, let’s start to learn how to play VOB files on Windows 10/11.
