Screencapping in BSplayer

I've been looking everywhere for something that will let me cap DVDs, and this looked perfect...but after I've right-clicked and gone to screencap, when I go to try and find the JPGs, they just...aren't anywhere. Eventually I asked it to save all the screencaps to the desktop so I didn't have to go through hundreds of folders, but...gaaah. They're just not there.

So tell me what I've missed...or what my computer is clearly incapable of doing. :roll:
