Other than being non-anamorphic the UK disc looked okay, its the muffled sound that was the real issue. I believe the Dark Sky sound is improved but I haven't seen it yet.
Also, the end credits state that the film was in Dolby Stereo. I couldn't tell if it was or not because of the sound quality and I think the US tape I have is Hi-Fi mono.
The US title card says 'there was a little girl' and the UK says 'madhouse'.
If it is the same source, then that would explain the replaced title card on the UK disc. The US video release was titled MADHOUSE with a different (and probably original) font than seen on the UK disc.
