I guess I don't have to compile anything different into the kernel. Do I just have to type a few lines at the prompt? I've tried: > > $ rmmod bttv > $ insmod bttv p11 > yup...that's the basics there. rmmod == remove a loaded module lsmod == list currently loaded modules (drivers) modprobe == load a module. insmod is usually only used if you compiled a module/driver yourself and the module is located in a folder other then the /lib/modules/<kernel version> folder. The module name needed for insmod is it's fullname, instead of it's abbreviated name (ie. insmod bttv.o.gz) modprobe is the prefered method and you can add your options in the /etc/modules.conf file. once you've made your changes in the modules.conf file, you can then issue rmmod & modprobe (without a reboot) for the newly added option in modules.conf to take effect. i'm not sure of the exact option your looking for w/o reading the bttv readme files myself...somebody else will probabely tell ya right off, but i just want to explain some of this stuff quickly. for the exact option(s) to add to the /etc/modules.conf file, see /usr/share/doc/kernel-doc-2.4.13/video4linux/bttv/* readme & options files. $ cat /etc/modules.conf alias char-major-81 bttv options bttv gbuffers=32 card=52 tuner=4 radio=0 As you can see, when my kernel loads the bttv driver, the options line will specify the options for the bttv driver to load at load time. btw. linux is not for the faint of heart. your need to do some learning to make things work perfectly. Although, it is very well worth what little work/research one has to do as it will also lead you to make wiser h/w purchases later on! oh, watch what options you specify as playing with the v4l stuff may freeze your box! learn the kernel hacking keys of alt-sysreq-s, alt-sysreq-u, alt-sysreq-b.
