This VHS preservation has one frame missing at the start of 4th reel,
which is present in althor1138's HF9G-TPM-LD.mkv.torrent

On the other hand, this VHS includes six frames missing from althor's mkv.
From the script's output:
146058 is a reel change
79498, 138108-109 are LD side changes
79250 & 80043 are neither-- they're mysterious mysteries ;-)

I don't like this movie well enough to try downloading althor's 60GB raw avi from usenet
