I have tried 
modprobe -r cx23885
modprobe cx23885 card=1

(which is supposed to be the driver specification for
Hauppauge WinTV-HVR1800lp)-- no joy. "lp"=PCIe.  I get no video or sound; tvtime warns it
can't find video0.

I have tried the patch at
http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-1800 with no joy.

I filed a Fedora/RedHat new Bug #515740 last night with much the same
information as given here.  No response yet.
