Updated my post above with the changes I found.
Someone pointed out to me on another forum how (oddly enough) Luke's saber is FIXED to the proper blue on disc 4. Why they didn't use this effect in the actual scene in the movie I'll never know...
It's also too bad that they didn't include the PC demo of Battlefront on here, as long as they were putting in the Xbox version. Every disc tries to install InterActual player and has weblinks to Starwars.com so it's not like the PC content isn't there.
