File "Open With" Association. Need to Revert or Fix

I tried to associate my VOB chapter files with WinDVD 7 on Vista 64 bit.

I used to drag them into the WinDVD player window to play them. These

files were associated with Windows Shell Common Dll for the "Open With"

command. I did what I did to cut one step out in regards to playing

them, and now they wont play!

I preformed this "Open With" change not more than 10 minutes ago...

Please help. How can I re-associate these files with the "Windows Shell

Common Dll"?

I can't find it on my PC.

Even better is there a way to Revert this change? sometimes these VOB's

I made would play and sometimes they wouldn't- I think it had something

to do with other programs being used at the same time. I use Zbrush

while I watch one of these VOB's Chapters I have. I use the vob chapters

for reference image study for whatever character I'm sculpting in

Zbrush.

Hopefully you understand why I need it too work like it did again,

soon.

Please help, Thanks:shock:
