I was just re watching version 2.5 and I noticed something out of place. I tried searching for it but found nothing. The issue occurs at around 18:50 and is in the scene when the Jawas come to Luke's home to sell their droids. We all know there is a funny shot when C-3PO is speaking to Uncle Owen and R2-D2 sarcastically turns his dome, as I was watching the scene I noticed the shot was missing, then at around 18:50 when the red droid blows his top and Luke says "what about that one" the missing shot is included. I was one of the early downloaders of 2.5 and I remember people talking about issues so it might be possible that I just downloaded a bad version.
