John,
Yes I have been on this forum for a long time.
Yes I am aware of Pal, NTSC, various speeds and all of Pedro's boxes and their costs.
I am also aware that Joerg Niggemann has been on this forum a long time and am very interested in his discovery of the use of computer software for syncing a GS-1200.
Joerg says;
"Sync signals for every speed (16 2/3, 18, 24, 25 fps) can be generated with nearly every sound editor program."

It's more expensive than the standard box but saves all the hassle of having to connect anything else other than this single box. It's a brilliant solution and if you're lucky enough to have one you'll never want to resort to anything else again.
I don't think having one of Pedro's boxes is a matter of luck. Also my computer and editing software were not obtained by means of luck. I can understand your not trying to sync with a computer because you already have a sync box, but others may find the computer method of interest and it may not be a hassle at all.

Dan, I can only encourage you to try it if you are interested.
After 4 years, I can say that I'm still using digital sound devices as crystal sync source for the GS and don't want to have anything else. A computer generated sync signal and a cable to connect headphone or line outputs to the GS is required. But once that first step is done, you have several options, even without PC. Here are two examples what you could do:
Build your own Pedro Box (very easy):
Burn your generated sync sound file to a CD. Play it back with a Discman, CD or DVD Player or other device. Connect the GS ESS input to Line or Headphone output and your Discman etc. will become a Pedro Box. Change from PAL to NTSC Sync by changing the CD/DVD. You could even think of coding your sync file into mp3 and play it back with an mp3 player. And voila, you have a "Mini Pedro Box".
Comfortable re-recording with PC (rough description of a quite complex but very quick workflow, additional Software required):
When re-recording a print, my PC provides the DVD movie with desired soundtrack(s), a digital copy of the S8 print (dv-avi file taken with camcorder) and the sync source signal inside Adobe Premiere Pro. All work is done offline without stressing the print and GS: DVD movie and S8 print can be seen side by side in a splitscreen while scrubbing through the timeline. Differences can easily be found and eliminated without watching the whole movie and without listening to any soundtrack. In most cases, it's done with a quick look over the timeline and a few cuts in the editor. Recording to the GS will be in perfect sync. You don't have to attend the recording process.
Finally, the project is saved to a Dolby 5.1 DVD which holds
- the GS sync pulse on its center channel
- usually german dub on front left/right channels
- original soundtrack on rear left/right channels
A DVD Player with analog 5.1 output can be used with this DVD to playback high quality dub or original soundtrack in sync with the GS (ESS input connected to center line output, Audio amplifier connected to front or rear left/right line outputs). No PC required for screening, only DVD Player and the GS.
A final word: I'm not claiming that the ESS circuit of any GS will work with any PC or DVD Audio output. But what I can say is that I've tried with three different GS Machines, Version 1 and 3 with a PC, a Laptop, several DVD player models, a Discman, a very old CD Player and different mp3 Players. There's a very good chance to get it working, but no promise that it won't be a hassle ;-)
Cheers
Joerg
