That’s not totally necessary since most if not all VHS’ of T1 use the standard mono as far as I know. The only exception was a few mid to late '80s VHS/Laserdisc releases which had the audio sped up. This was an early attempt at converting the mono track to stereo but the results weren’t that good. This was called the ‘Fake Chase’ mix or something like that. That mix was mentioned some posts ago. However by the early 90s the corrected pitched mono was reinstated and was kept as the default until the 5.1 mix was introduced in 2001. That being said, I’m glad that the mix that was preserved by these guys was the one they used. It’s much more tougher than the mono track given by MGM and I like that some effort was made to make it sound better than just a LD mono track synced to a Bluray.
