I live in Brazil. The electric frequency here is 60Hz, and not 50 Hz an in
Europe. So, pal-m uses the same framerate and resolution of ntsc, because in
America the electric frequency is also 60Hz. To the best of my knwowledge,
pal-m uses the color system from the pal system and the frame rate and
resolution from ntsc. Please, just check the link below.


Furthemore, if I do not use any FPS option (it is not really necessary), the
capture from the TV is 29.970 frames/sec.

As I said before, if I capture directly from the TV using LAVC, the image is
pretty good and there is no buffer overflow.
