I hope my cropping&resizing information helped, Andrea!

Darth Editous has confirmed that my calculations were correct using a different method, so I hope you'll trust what I've posted.

The hardest part of all of this is IVTC'ing. Automated methods really don't cut it, especially if you plan to sync to GOUT. Darth Mallwalker is the IVTC master around here, so I think he'd be more qualified to help out with this particular aspect of your preservation(s). I don't know if he'd want to, so it'd be better to ask him.

Antcu, can I count on your help if (when) needed, for what concerns AviSynth and/or VirtualDub scripts and settings?

Yes :-) My real name is Anthony, BTW.
