Strangely enough, the tv broadcasts and dvd versions are higher pitched around germany than the original vhs tapes, which had lower pitch.

Interesting, I didn’t know that. That means:
By the time the series was brought to Germany it was often practised technique to convert from NTSC to PAL in a mix of blending and keeping the original interlacing, especially with such mix-content of pulldowned and native 29.97 material.
So they seem to have dubbed it in its original length. This is what is also on the VHS cassettes.
The newer masters for the DVDs were carefully IVTCed (and the 29.97 portions brought to 23.976 in I-don’t -know-what-way), and then sped up to 25fps. Then they sped up the sound without correcting the pitch to its lower original. So you are damned right when you pitch down - even better would have been to slow down to 23.976 and then simply resample the German dub down, pitch would be corrected automatically and everything fine!

As for the speed down to 23,976 FPS: That would cause motion stutter again, which I was happy to have avoided with PAL at 25 FPS.

That’s an error. Slowing down does not at all cause any stutter, if you do it right - that means the very simplest way. Try it with avisynth with, as I said:
new=assumefps(old,24000,1001)
This will just change the SPEED, no t one frame will be added or dropped.

I can confirm what FrankB has said here. In fact, I experimented with doing this.

You can slow a PAL broadcast from 25 to 23.976 fps and never notice that you’ve done it. Then you can pitch-shift the audio down by 4% or get yourself the NTSC discs. Either works. I tried stapling the NTSC audio to a PAL rip that I’d performed this on, and while I had to add a 1.2 second offset to the track, it worked perfectly for alignment once I did. No stuttering.

This is why I seriously considered using PAL instead of NTSC for my project.

It’s certainly an interesting idea. Any way to accomplish that with StaxRip? I have zero experience with avisynth.
