I've seen the extended editions that play on TV, which for some reason were never released on physical media besides movies 1-2, but it looks like JJPotter went beyond just adding back in deleted scenes since he cleaned up some of the effects as well. I would definitely be interested to see his versions! I already own at least two copies of each movie, not including digital. It's just a shame that WB is sitting on so much deleted Harry Potter material that has never even been released to the public. I'd definitely repurchase all the movies again if they did include more deleted scenes.
