VISTA USERS: go to c:\Users\YOUR_USERNAME\AppData\Roaming\vghd\models )"
That's the information for backing up the girls - basically, where the various data files are kept. If you want to figure out what card is which show, you may want to try launching a file directly from that folder. I have not done that myself, but I would assume it will launch VG and play the associated clip. Once you find the clips you don't like, simply delete that file. The other clips will remain and, unless I'm very wrong in how the system is coded, your VGHD application will be none the wiser.
