[mythtv-users] WinTV (bttv) and PVR150 (ivtv) apparent conflict

Tue May 31 00:06:36 UTC 2005

I don't really know much about this but I thought I should add that I had to 
switch my WinTV (bttv) and PVR150 (ivtv) cards around in the PCI slots to 
get them to work properly. In other words, it is sensitive to which comes 
first. I'm not much of a linux expert so you might be able to address this 
with the modprobe configuration (and for all I know, perhaps you have). All 
I know is it was necessary for me.
