I've been having the same problem (when leaving Irenicus' dungeon, after the cutscene, a second cutscene starts with nothing happening and hangs) and i tried the solution mentioned above, but now the actual ROT cutscene is gone completely. I tried restoring the 2 edited files to what i think they were and it still won't come back, which makes me think I buggered them up some how. If someone could just post their working entjc3.bcs and TELE0700.bcs, that might be all it takes. Oh and also, the StartCutScene("cut01") that I was supposed to delete from entjc3.bcs wasn't there to begin with, don't how significant that is.
Nevermind, i just had to start a new game and then it worked
