Linux; open ("/dev/video"); tvtime boot-up default

Hi,

I have a BT848 PCI grabber card.
A program using open ("/dev/video")...mmap (...) works only
after running program "tvtime", which somehow sets parameters:
cap.maxheight, cap.maxwidth to something other than their
boot-up default values. How do I set these? There is no
VIDIOCSCAP defined in "videodev.h" for use with ioctl()?

Thanks.
