<div bgcolor="#FFFFFF" text="#000000">
Like you, I have Comcast, and like you, I found that nothing I did
would make channel changing work through firewire. I recommend using
an IguanaIR IR blaster, you can get it from their website
(<a href="http://iguanaworks.net" target="_blank">iguanaworks.net</a>) for $40. My script is here<br>
<a href="https://code.google.com/p/mythtv-scripts/source/browse/trunk/install/opt/mythtv/bin/channelchange.sh" target="_blank">https://code.google.com/p/mythtv-scripts/source/browse/trunk/install/opt/mythtv/bin/channelchange.sh</a><br>
Other necessary scripts are also there. The IR channel changing is
100% reliable with these scripts, and you just point mythtv to the
external channel change script /opt/mythtv/bin/channelchange.sh. The
script takes care of a number of glitches that can happen, like the
Iguana service failing, lirc failing, the set top box being turned
off etc. One thing that DOES work with the Comcast set top box is
detecting through firewire that it is turned on.<br>
<br>
To use those scripts a number of things need to be set up - iguana
service, lirc, etc.<br>
<br>
Since tuning the set top box with an IR blaster takes a few seconds,
I set in mythtv the option to start recordings 15 seconds early.<br>
<br>
A small tip - you can use the set top box built in "VCR timer" to
set it to turn on at the correct times for the programs. You can see
the upcoming program list on mythtv and set the set top box to tune
the correct channels at those times. However this method is really
only for emergencies since it is very tedious and you can easily
make mistakes.<span><font color="#888888"><br>

This is really awesome thanks so much. <div><br></div><div>I've already started messing around with setting up a IR Blaster using my MCE USB Kit (that came with the WINTV HVR 1600) and I have no plans to buy anything new at this time. That being said will your scripts work with the "mceusb" remote? I downloaded the "LircChannelChanger" one last night "<a href="http://www.mythtv.org/wiki/LircChannelChanger" target="_blank">http://www.mythtv.org/wiki/LircChannelChanger</a>" and started trying to get it to work from the command line, but the STB didn't seem to respond.

which I'd recommend starting with since it uses the (probably more

trying to get my IR Blasting working with my MCEUSB Kit. It uses a
little IR Transmitter which connects to the back of the USB transmitter/reciver. The remote controll works fine with my MythBox. And IRW shows me it's receiving commands. I was under the
impression to get IR Blaster to work so I could change the channels on
my STB Box (Cisco RNG 150) I just had to point it at the Cable Box's IR
Reciever and it would work. Im mean once i got it set up correctly.<br><br></div>So here's some help stuff.<br><br><br></div><div>IRW <br><br>000000037ff07bed 00 KEY_CHANNELUP mceusb<br>000000037ff07bed 01 KEY_CHANNELUP mceusb<br>
