I must again emphasize that for tallying and voting purposes the decisions should be made 5 or 10 at a time. It would be much easier and people would not be intimidated from voting.
PS: I remember someone posting that they had the high quality copy of the 1997 SE that they used to show the movies on TV. That should be the reference used for putting the original Anniken at the end of Jedi not the laserdiscs.
Using the upcoming DVD sound track would be a good jumping off point to where you can take out SE audio and replace it with the original where necessary. As for menus I use them all the time because they are faster than hitting skip 20 times and they are more visually pleasing. Menus that opened with "a long time ago...STAR WARS" and then transition to the menu with some of John Williams brilliant score would be worth losing 50-100 megs of space.
Could you post some screen caps.
