As I suggested back on page one the only way I can think of making the Jabba scene work is by changing the subtitles so he says something new (and if Jabba was colour and light corrected and someone sorted out that bleedin tail).
Harrison is very good in the scene and having Boba in there adds a certain something (it's a pain that Lucas seems to have Fett as more of an henchman to Jabba in ROTJ which in the round is compounded by his appearence here but....) away from that it's like he was saying "Ok you've got your last chance but look what's waiting for you if you screw up this time".
That's a lot of ifs and buts for a little more charming rascal but perhaps someone could pull it off as a mini-project which could be inserted in to edits by those who want to.
