Thanks for trying to help. 25 frames per second is the PAL standard,
it's by the book and by the google that anyone, as far as I had searched
earlier, capturing PAL VHS on composite input do (some even recommend
-fps 50)...
I guess the Windoze also have 25 fps assembled in the program that
captures composite...
What command do you use for capturing VHS on composite/S-Video input of
your card?
