I have been watching the clip again and there is one more audio mistake from the original.

C3PO again "well don't blame me, I'm not supposed to know a power socket from a computer terminal"

His voice volume stays the same even though he is being carted off by chewie. This really sucks you out of feeling like you are there and obviously shows itself as an overdub audio sample. Could his line be faded out in volume as he is carted away by chewie. In all the other shots it's not an issue but as the camera is static and he is getting much further away from us it really pulls you out the moment.

And of course none of the stuff I have mentioned is the teams fault. On this section of Lando's announcement and the running I felt pulled out of the film on numerous occasions. But like I said it's not a revisited fault. It's the movie that you are working with that did that.
