I dont see a module parm to set that.
I downloaded the data sheet. It should discover the correct standard, except I think it can't tell NTSC-M from NTSC-J. How is the AFD_NTSC_SEL set? Do you set that explicitly, or is it done in the CX25840 driver? It would be a cheezy workaround, but if it were available to change VBLANK_CNT_LO and VBLANK_CNT_HI using the /sys interface, that would probably work. If that is fairly easy to try, give me a hint where to look in your driver and I'll try.
