I just bought Magical Mystery Tour Media Home Entertainment vhs, dated 1985 for the original mono mix. Not sure if you noticed or not, but it runs 4% slow. This must be sourced from a PAL video transfer. The same thing happened on The Doors 1998 “Doors Are Open” dvd. They corrected the speed issue when it was re-released on BD in 2014.
It’s possible that it is from the PAL if it’s running slower. There was a theatrical print in the US distributed by New Line Cinema in the 1970s, so I’m surprised Meida didn’t use that.
The BD will be at the correct speed, but it’s a whole new mix (stereo and 5.1) done in 2012 by Giles Martin.
The original mix is easy to spot because it will have John’s overdubbed “Roll up! Roll up! For the Magical Mystery Tour…” at the beginning of “Magical Mystery Tour” rather than the recording from the song. It also contains the original mono mixes of the songs.
