As far as framing goes, the final images will have all the information that is on the laserdisc, some of the images on our site or captures shown here will vary greatly in framing, zoom level and so on.
This is because I am at this stage literally doing a braindump of experiments as I go along, these aren't final images by any stretch of the imagination.
Sometimes you might just get a small part of an image if that is what I am working on at the time.
That is also why the images are from Jedi this week, it is what happens to be on my drive at the moment. (I only have room for one film at a time).
So you will see square pictures, 16:9 pictures, chunks of pictures, full frame pictures and all sorts of things along the way. There is no official DVD compare shots from me, except in the tutorials for the purpose of education - someone else threw up the dvd image last time. (I don't have the NTSC DVDs, only the Australian PAL set.)
On the subject of missing information one thing to keep in mind is if you are watching DVDs on a TV, (unless you have adjusted you set to show a full frame) you will only be seeing the "safe frame" area, and will be missing a large amount of picture off the left and right of the screen.
At one stage I considered the idea of moving the entire picture into the safe frame of the screen, but the loss in resolution makes it an unpalatable option.
As for anamorphic, I am defiantely going to do some animorphic tests once the archiving of the letterboxed laserdiscs is bedded down.
I understand that sometimes it is better to have resized the source to animorphic as well as is possible - as some displays mess up a letterbox source.
