Did I ever respond to this in any way? I can't even remember reading it...
Well, I don't really have a usable build of Lurch, it's just a hardcoded test where it processes a series of interlaced tga images placed in some folder and spits out processed tga images in another. That's how I remember it anyway. On top of that, I changed the code around to tweak it for specific video sources, and it's likely that the current version has some broken preliminary features in it. Not to mention that it takes forever to process even a short clip.
You're better off looking for a demo version of some commercial software that does the same trick but better and faster. Search for "ReTimer" for instance.
If you want to look at the source code for educational purposes, that's another deal and I could send it to you if you email me about it. The program really isn't suitable for actual use though.
