You didnt do anything wrong. Those are just some of the changes that Lucas has made to his movie. Just go check any DVD/Movie forums to read geeky comments on why Lucas should have released the Untouched Trilogy (shut the **** up you fat homos, know one gives a **** about your opinion. Just keep dressing up in your Star Wars costumes so everyone else can point and laugh). If I wasnt so tired I would go check my dvds, but I dont want to spoil them, until I sit down and watch them properly
Of course, I could be wrong, and you could have messed up your rip.
