-So if you look at the scene where Hichigo "retrieves his sword" and slices the ground orihime becomes thrown, but in the PSP version she's just there. If you watch carefully you'll see the difference. By the time the rocks are falling (ground parts) when running both videos side by side it's two different scene's.
-Every time Hichigo does the scream it's different, the swirling red colors and the back drop on the actual episode vice the "PSP" version.
-When Ulquiorra makes the "Lanza Del Relampago" for the first time there is he has yellow green eyes vice pure green eyes.
-When Ulquiorra throws the "Lanza Del Relampago" at Hichigo in the "PSP" version he "flash steps" to behind Ulquiorra but then in the actual episode he moved to the side dodging it, then when his hair is waving in the air due to the explosion he performs the "flash step"
-When Hichigo swings his sword at Ulquiorra in the "PSP" version after the "flash step" and Ulquiorra jumps away, in the actual episode that scene doesn't happen till Hichigo comes in from the ground swing and then Ulquiorra jumps away.
-When Hichigo blocks Ulquiorra's "Lanza Del Relampago" with his bare hands in the "PSP" Version the back drop is the black night sky but in the actual episode it's part of the crubled tower.

Those are all the difference's that I can see plainly. So if it is "RE-used" they spent a lot of time changing a lot of the stuff in it.
