Hello,

My Silicondust HDHomeRun DUAL (Model: HDHR-US) ATSC tuner that I was using
for over a decade to receive and send IR signals to my MythTV box via UDP
(port 5000) has stopped working.

I have a Raspberry Pi in the same TV room that has a working IR receiver on
it so I was hoping to reproduce the function of the HDHomeRun DUAL's IR
receiver using the Raspberry Pi.

I cobbled together this command on the RPi, hoping it would send the IR
signals to the MythTV computer in the same way the HDHR did but it doesn't
seem to be working.  I'm running irw on the 192.168.1.2 computer but it's
not receiving any signals.

/usr/bin/mode2 -d /dev/lirc0 | irtext2udp | socat - udp-datagram:
192.168.1.2:5000,broadcast

I'm hoping someone else has done this or has experience with it and could
offer me some assistance please.

Thanks
