[mythtv-users] How to force ivtv.o to initialize the correct card?

Sun Oct 10 09:29:44 UTC 2004

A couple of ideas:

* switch the cards around (change their PCI slot order)

* force the system to load the ivtv driver prior to bttv. On my gentoo
box I do this by adding ivtv to /etc/modules.autoload.d/kernel2.6
YMMV. This loads ivtv AND bttv since ivtv needs some parts of bttv.

maybe one of these will make a difference....
