How do I enter IR Blaster codes?

Yes, I am this dumb. I went through all the menus and I don't see any option for telling it which IR blaster codes to use. Couldn't find it in the user's manual or searching this site either. I did see a fair bit of stuff about how to add new codes to the box, but nothing on simply entering an existing code.

Also, any hint on what codes to use for the new Comcast digital service - or how to find out? I sort of figured the DTA (digital converter box) docs might give me the correct code - but not so much.

Thanks in advance.

Thanks very much! I'm in a "chat" with Comcast right now. They suggested code 991. I'll look for those threads.

Looking through the threads I see that this topic is easily found. I managed to do a really lousy search apparently. Thanks again.

Thanks again. I was able to follow the excellent instructions to download the custom IR blaster code (1982) and get my networked unit working. Tomorrow I will update my dialup unit. Figuring this out on my own would have taken longer than I have left on this earth.
