I too am having 0 signal strength with a Fusion HDTV 7 Dual Express.  scan 
(from dvb-apps) does find channels, but my application won't work because 
it is seeing no signal.  I tried rebuilding the drivers from repository 
tip but it doesn't help.  The kernel I'm using is 2.6.27.9-73.fc9.i686. 
lspci -v shows:

02:00.0 Multimedia video controller: Conexant Unknown device 8852 (rev 04)
         Subsystem: DViCO Corporation Unknown device d618

after "make load" in the v4l-dvb directory  dmesg shows:
