First Transport is Away doesnt have CGI anything. There aren't CGI ships outside of ANH (minus the Vader shuttle). I'll have to go over it again.

These SE X-wings definitely look CG to my eyes, this is the only sequence it could be. There are also other places in the trilogy when they used CG-models for the SE.

This one in your Jedi comparisons is not an actual change/retiming of the scene, just another case of the splitscreen-DVD not being synced up exactly, probably due to different frame counts between the transfers.
