I actually saw your threads weeks ago in my googling around for solutions, your talking about that hugging-the-top/uncentered issue . No, it's not the same thing -- and I, too,wouldn't mind having the captures moved down a couple of lines at least. Too bad no one responded to your thread.

Posting screen captures here wouldn't show nearly as much as your seeing two short avi clips compared overlapping style in VDub... but still, here's pics of exactly the same frame of video capture...
I captured the clip 8 times. Most of the the caps turned out with this cut from the one shot to other looking like this:

Okay, that cut is interlaced. Fine. However, a rebel group of the captures have the same cut clean from the one shot to the other (this here being the "cut to" frame of course). And all of the captures in this style are one scanline lower than in the capture style above:

Theoretically, all the captures should look basically identical except for very slight noise changes, but that's not what I get. (I won't describe it again as I've already gone through it in detail twice above in posts.)
...to compensate at the capture stage so you don't have to average it out in avisynth.

Knightmessenger, have you done multiple caps of one thing and gotten the differences talked about here in those captures?
