Frank, I get what you're saying. Personally, I found that setting the hue a couple notches to the left of the right edge helped the skin tones a tad.
Anyway, to get this back to the subject of the bootleg itself, one thing I noticed is how good the *sound* is. For non-hifi mono, it sounds excellent. If I use the equalizer in VLC, I can bring out a surprising amount of detail in the high and low frequencies. (Of course, turning up the treble also increases the hiss, but there *is* high-frequency information under that hiss.)
My point is that the sound quality is too good to be from a 16mm print. 16mm prints were in non-Dolby Academy mono, and thus had narrower frequency range and lower fidelity. The non-Swedish print used in Puggo Grande actually had a mono fold-down of the stereo mix, which Puggo replaced with the mono from the Swedish print. You can hear the mono fold-down of the stereo mix in the Catnap bootleg.
I compared the audio of Catnap and PS78, and Catnap sounds really tinny in comparison. That's what a mono-fold-down 16mm print sounded like. If PS78 were from a 16mm print, it would sound close to Catnap. In reality, PS78 sounds to be sourced from Dolby Stereo, and thus from a 35mm print.
