Not sure what worked for me, but this is what I did (read it on Xbox-saves.com)
I did the ini thing above and it didn't work, so, I saved right before the terminal, go back to the menu and quit the game, goto Movies and select the sith trailer. Sit through and watch it (I know, sounds stupid) wait until it's finished and returns you to the menu, and then go back and load your game, and go through the terminal sequence, it should go black and then go to the autosaving screen. Hope this helps.
