Success! So after playing around with Irrecord last night I was able to
create my own lircd.conf for my RNG150 and after adding that to my
hardware.conf was able to successfully change cable channels and power the
STB via the LircChannelChange script using the IR Transmitter. It works!!!
The lircd.conf files that I download online for my STB didn't seems to work
which leads me to believe that my Cable Box is probably not really the
correct version or brand I think it is. Who knows?

Also the Cisco RNG150N does need a IR Receiver to work. It will not accept
commands otherwise. I know this makes no sense, but I tried it both ways
and it only works with the receiver plugged in. The forum boards at Comcast
at this one correct. If someone knows the reason why for this Iove to hear
it.

Anyhow, this is great news, since I just ordered an HD PVR 1212 (from eBay)
and plan to set that up and try it out next. I also think I'll add some of
my findings to the MythTV WIki because to be honest half the problems I've
run into are issues that weren't on the wiki.

That being said. Thanks to all for your advice (it really did help a lot)
and sorry for the long email thread
