Missing "Nero Digital" Properties Tab

I got into the habit of viewing some of my mp4 ND files using explorer because the icons would automatically tell you if it was a Nero file and what profile was used to create it. I also like to check out the properties under the “Nero Digital” tab to view the specs.

But for some strange reason I have another computer which only shows the showtime icon with no ND properties! :doh: Is there some easy fix for this. I’m assuming it has to do with some sort of file association.

FYI: I’m running Windows Vista Ultimate…

Thanks Bugs…
