You have not mentioned what happens when you play the file with VOB extension.
Does Media Player give you some message or it opens in some other player?

Make sure media player is the DEFAULT player of VOB files.

To check it, right-click VOB file and click Properties.
You'll see the default player as:
"Opens With: Windows Media Player"

If it's not Media Player, use the Change button to change it.

I hope it will work.
