I got the CD ripped to 320K MP3s and can now see the waveforms
as generated using Audacity. I can also change the speed.

There are two copies of each short movie except 1 and 18,
the second ones being inverted waveform and you add 17 to the
track number. Using my computer the 1st set are correct.

At least most of them sync much of the time. It also helps
to change the audio volume from the computer.

However, it appears that the vertical (line) sync is exactly
off phase: the bottom and top of the picture and the black bar between
are right in the middle. I don't think this can be fixed without a new paper disk to glue in a different orientation.

I found that pushing the disk closer to the circuit board (and thus
the paper sync disk with black and white areas closer to the sync LED and detector) makes it work better,
but still not good enough. I can't make it closer as it would scrape the screw heads holding the LED and
screen. I will try to get some flatter screws.
