Made the caps. Since I have trouble with printroom sometimes, and since it only presents pictures over a certain size at full resolution if you're the owner of the album or have been granted special access, I made a password-protected album.

Although out of order, you'll see the entire movie frame and also a blowup of the saber within that frame. Contrast was adjusted for the blowups.
If any photoshop gurus would like to try additional tricks, I will gladly email you the unaltered .tiff files I saved the complete frames as. (Blowups exist as .jpgs only.)
Verdict? Not sure about the "missing" grip, but I do count four visible grips in several instances, with gaps narrow enough to support 7 grips IMHO.
There are a few other pics in the album you can just ignore.
I welcome any additional efforts from other cappers out there, but be aware a DVD boot of this same LD source will have undergone compression so the caps won't turn out any better. In the end we're still talking a 720x540 image, with the saber only a tiny part of it.
If anyone has a PAN AND SCAN LD of ANH, as someone suggested, we can get higher res caps.
Feel free to link and post away with these pics.
EDIT: Looks like my little trick didn't work, it still won't show the complete movie frames at full res. Oh, well, the blowups seem to be okay.
