Well, I went back and reinstalled all the ivtv stuff and now something
different happens. When I select Capture cards from the mythtv-setup
and then new card I get a seg fault. This happens on 0.18 and on CVS
from about 2 weeks ago.
Any ideas would be great!
As far as I can tell ivtv is still loaded and active.
This from dmesg...
