If you enter a UPC number that isn't found, then in the dialog box that pops up to ask you the title you select the "Edit Profile Now" box, the profile edit window will come up (which is correct).  However, if you use the arrows in the bottom right corner to progress through the screens you'll notice you get past "Box Set Contents" and get to the "Cover Scans" section... and the "Cover Scans" tab is not along the left side of the box with the other tabs.

"Cover Scans" correctly appears if you edit a DVD profile once it's already added to your collection.  (The defect being reported is that it's missing from the left column; either it should be added to the left column or the "Cover Scans" section should be skipped during that initial edit phase.)
