Hey, im trying to create some movies with avidemo's and can create the screenshots but the folder is locked and I cant open it in VirtualDub. I know the screenshots are there because CoD4Player can open the folder like so

Thats in cod4player and it has that little lock icon on it.
If I go to the same spot in VirtualDub, its hidden.

So as you see there is nothing there, can someone help?

See if you can change it to compatibility files when you're looking for it in VDub.

And how would one go about that?

Got the same problem when I tried with avidemo.

I've just put all my screenshots on a folder in my destktop and then I've done my video.
