@Karl Hey thanks so much for the feedback. I came to the same conclusion
after some more online research and more trial and error and added the
correct lircd.conf without any luck. But as I discovered last night the
issue is not with the Mythbox or MCEUSB Receiver/Blaster but most likely
with the STB.
According to several entries on the Comcast Forum my STB will not receive
any IR Transmissions without an additional IR Receiver that needs to be
plugged into the back of the STB.
"to use the RNG150 box with any ir blaster device, you need to go down to
Comcast and ask them for an IR Receiver that plugs in to the back of the
rng150 box (they come with the little dta boxes already).. mount it on the
front of the rng150 with the pickup from the ir blaster and it will work
So this afternoon (on my lunch break) it's back down to the Comcast Center
to see if they have one of this things.
Has anyone else run into this issue with any Comcast STB boxes. Again mine
is the "Cisco RNG 150N"
