If you're trying to GOUT sync your captures, then the master you are synchronising to is the GOUT; the 2006 DVD 'bonus' theatrical edits, which are the masters for the 1993 THX releases of the films.
You can either use IVTC plugins for AviSynth and can do a good job of adjusting with pulldown pattern changes, provided they are set up correctly (TIVTC does a decent job). Manual IVTC can be difficult at first, depending on your experience level with AviSynth. The DoubleWeave() and Pulldown() commands are what you would be looking for, although not particularly well documented for beginners. There is also the long-winded SeparateFields()/SelectEvery() method, which can be easier to understand but lead to long and confusing scripts when you have a lot of pattern changes.
I don't know of any simple guides for this other than to suggest that Google is your friend, and there is a lot of useful information on various forums of people asking how to perform an accurate IVTC. That's how I learned to do it.
Which Laserdiscs are you trying to GOUT sync? There are hundreds of frames missing from some of the Laserdisc releases, so you may find GOUT sync impossible...
