Thanks for your help and suggestions, guys (especially Kexikus)!
A good number of those modifications I can no longer provide links for since they were hosted at Filefront but I will try and answer HH's questions about some of them.
Kreia's Fall: it is a HQ version of Kreia's Fall cutscene made by danil-ch
Kreia's Lesson: This is a modification to Kreia's global dialog. It restores a few lines to Kreia's dialog about small kindnesses and cruelities. Again, made by danil-ch (and Darth Hayze)
Nihilus/Visas scene: This is a modification to Nihilus/Visas scene. This file replaces some of the Visas's lines (5 of them) with the ones that been used in pre-rendered cutscene. As usual, danil-ch is the author.
Roleplay in 103PER & 304NAR: Made by Achilles. It changes the speed of the so called Space Walk so that it feels you are really out in space.
