Nice job, doubleofive! Those saber impact flashes in the battle looks horrible in the DVD, if you look carefully, you can see they only have the core left, and a very dull core that is, what happened to the outer glow? they don't even look like flashes, more like a light-green mess.
Also, all those Vader vs. Obi-Wan changes are 2004 alterations, I compared the '97 transfer with your finds and the flashes are identical to the original film in that one.
