HDPVR IR Blasting to a Comcast Cisco RNG150 SetTop Box

[pla]

Hey Folks

I get most of my content OTA via HD Homerun and antenna in my attic. I'm loving the OTA content but I wanted to get ESPN HD so I picked up an HD PVR 1212 from Amazon for $169.99. I got a Cisco RNG150 settop box from Comcast. I'm new to IR blasting. After searching a bit I get the impression that the Cisco RNG150 is kinda new and unknown. I've tried setting the IR transmitter to a SA cable box but it doesn't change channels. Does anyone have any recommendations on where to start so I can get channel changing working?

Rock on, PLA

Which blaster are you using, the PVR-1212's? If so support is a bit sketchy at the moment. Whatever IR blaster you use make sure it's functioning correctly. I assume you did a search of your STB model & MythTV? If nobody has come up with a working lirc.conf file for that particular model STB then you're going to need create your own. You can record the keys by using the irrecord command. Here are a couple good guides:

As a point of reference I created this wiki entry a while back for my old Motorola DCT-700 cable box:

Once you have the IR codes recorded you should be good to go. Keep a backup of the file as it may be overwritten anytime you update your mythbuntu box. Finally share your working configuration by posting in mythtv-user mailing list, mythbuntu forums and maybe create a wiki entry on mythtv.org.
Let me know if you have any questions.
Good luck.

pla, also keep in mind that if the cable box supports it, Firewire changing is 99.99% reliable.
Does this cisco box have a firewire port?

If you have to generate your own codes, the HD-HR is the gadget I use to generate all my codes from my hand held remotes using irrecord. It really is quite good for this.

I'm currently doing firewire channel changing for the Motorola DCX3200 cable box RCN provides. It works pretty well.

Thanks for the great tips and resources Pat. I'll be diving into this after I cut the grass.

The Cisco RNG150 has a firewire port. I'll check it out.

Thanks, PLA

I'm exploring fireware for channel changing. I guess I"m going to try the 6200ch command. I'm also looking at this post http://ubuntuforums.org/showthread.php?t=977820 by majoridiot. Am I heading down the right path? Any tips for firewire channel changing?

Thanks, PLA

Got it. I'm using

Code: Select all

/usr/bin/mythchanger -f 6 -c 

.

Pat and marc, are y'all using mythchanger too?

Yes, I'm using mythchanger

I am also using mythchanger, but I have a scientific atlanta box and use this code.

/usr/bin/mythchanger -f 4 -c

Has worked 100% so far.

Pla:

Yeppers, I took spotslayer's recommendation and use mythchanger with a wrapper shell script to control two boxes.

Works fine with only one time I had a mix up by going to the wrong channel.

Near perfect
