I will read the german part of your post tomorrow, it's too late for that now.

In case of a capture chip based correct internal µs related resizing in FitCD, ... that would mean you would have to add a "used Capturecard chip" Gadget, ... right?
Sort of. We just need to add an active capture window box. That's all.

AIK there's still a bug in that old FitCD release related to the correct NTSC 528/544 Target PAR, but maybe Im wrong.
Oh, I don't know. I will ask shh about this.

Und jetzt kommt eben das was mich stutzig macht: Wenn ich z.B. mit einer 53.3333 µs arbeitenden Karte auf 704 beim capturen gehe, würde sie dann auch jene 9+...+9 lediglich auf 704 runter resizen und nicht croppen??? Denn dann wäre dies eben der Knackpunkt. Hmmmm .....
Remember a cap at 720x576 or 704x576 is just a scaling of each other.
I will adjust example 1 in section 5.6:
1) Say you want to make a DivX/XviD (PAL). Full PAL TV on a PC gives 52 µs * 14.7692 MHz = 768 pixels, ending with 768x576. Your "SAA7108, Nvidia with a WDM driver" has a capture window of 53.33 µs. So, how many PC sized pixels fit in the capture window? 53.33 µs * 14.7692 MHz = 788 pixels. So you have two options here (however, if you can't capture at arbitrary sizes you only have one option):
a) Cap pixels that are at or close at the target size. That's not always possible.
b) Capping at another resolution and resize to the correct pixel size afterwards. If you want that, cap high, say 704x576.
However, your card caps only 53.33 µs, so you need less pixels to make up the difference with the 52 µs a PC needs for correct AR. How many?
(52 / 53.333) * 704 = 686 in total.
So, remove 704-686.4=17.6 ~ 18 black pixels of your 704x576 cap
[*]. You now have 52 µs of info in 704 pixels. Resize the resulting 686x576 to 768x576 or a scaling of it.
[*] If you would have capped at 720x576, you get (52 / 53.333) * 720 = 702 and you have to remove 720-702=18 black pixels of your 720x576 cap. Resize the resulting 702x576 to 768x576 or a scaling of it.
I hope it's a bit clear ?
