[mythtv-users] Need Help configuring Capture Card/Video Device

[Kent Rigby]

I unistalled the IVTV rpm (v0.2.0) built v0.,4.5 and installed that according 
to the directions on the ivtv web site.  But for some reason it would appear 
that my system is still trying to load the v 0.2.0 modules. This is what I 
got from dmesg.  I am baffled about this.
