The fullscreen THX TSWLM has a very tiny bit of extra on top and bottom, but the pan and scan job loses a great deal of picture. Reminds me of my childhood VHS days. (I still have these to be honest.)
Did you guys notice any loud pops on the OHMSS audio? I had a few towards the end of the film that sounded more like pops on the track itself and not the source audio. But the sound is stellar and surprisingly so. Very dynamic.
The truth is that the original audio is only provided to purists because it is a common thought that original audio is antiquated and inferior. Home video is done for the biggest consumer group: Mr. Joe Video who wants a great bright and shiny picture to fill his TV screen and 5.1 surround to play on his home theater in a box or multichannel crummy soundbar.
Thus everything will have a 5.1 mix done, when to be perfectly honest it never sounds as good as the original. These mixes were done with the original materials at the time of production, with everyone's intent being to make the material sound as good as possible. They weren't intending for discrete modern setups because THEY DID NOT EXIST. On top of this, modern remixers have no connection to the film and usually are given a tight work schedule and no background material.
And DD 192 kbp/s is equivalent to a low bitrate mp3, I don't care how many tell me I'm wrong on this but it's important the original audio be given necessary space on a disc to at least have breathing room.
