Thanx4the response Andrea. Sure, I can post sceenshots of the "trouble" areas (there a lot of them in some episodes, but for example so you can see what I'm talking about, here's a few where first I'll post the trouble spots that don't have duplicate frames that I can use to correct the problem with the proper transfer examples of those frames underneath):

01- problem frames

correct frames:

example 02 - problem frame:

correct frames:

example 3 - problem frame:

correct frames:

example 4 - incorrect frame:

correct frames:

Unfortunately, it's more than just a few frames per episode (fortunately it's only a few episodes, as most are correctly transferred to PAL) I am trying to fix them as best as possible and want to go for a "purist" version, if possible, and you're right that most people won't notice (but I will)

As far as scripts are concerned, it's something I'm still learning and most (but not all) of the editing work (after I deinterlaced the videos using a script in avidemux) is being done in Vegas Pro 11.
