I have looked at , (1) The Directors cut DVD 177 minutes, (2) the B/Ray, Extended Edition, B/Ray ( Which is not what it says, it's only 136 minutes long. It's extended by a 3D version and extras. NOT A LONGER FILM.) (3) The TV B/Ray extended version, sold as by David Lynch in adverts and on the BR sleeve, but is not. As the film rolls you see it as by Alan Smithee, David Lynch refused to have his name on this edition, you would see why, really crap VHS type image, 177 minutes, only 4.3 square frame, not wide screen and stereo only. (4) Bar code version (5050582888065) so you get the right one.Now this version.It's the very best, actually by David Lynch, true Blu-Ray, excellent image, wide screen, excellent sound and nearly what I was looking for. I wanted to replace my extended edition (177 minutes ) on Blu-Ray. It dose not exist, i'v actually tried the lot,USA, UK, Germany and this is the best all round current version.
