Just to confirm that the HDHR is still sending packets you can try this:
At the console as root with lirc not running start mode2 with this command:
mode2 -H udp -d 5000
You should be able to see the output of your remote presses.  You can 
also run irrecord via udp with this command:
irrecord -H udp -d 5000 -n testfilename  (also with lirc stopped) file 
ends up in "root"

I'm running Mythbuntu, so I'm not familiar with Fedora.  I let Mythbuntu 
install and run lircd for a generic remote.  After configuring the HDHR 
properly,  I then configure lircd by modifying "/etc/lirc/hardware.conf" 
for the HDHR by adding/modifying these lines:
REMOTE_MODULES=""
REMOTE_DRIVER="udp"
REMOTE_DEVICE="5000"
REMOTE_SOCKET=""

Again, I don't know if Fedora uses a hardware.conf file for lirc or 
not.  If it does, maybe it is conflicting with the command line switches.

If the mode2 command doesn't work, then your problem may not be related 
to lirc, maybe you have some sort of  firewall or network problem.
