Comcast Craziness

I installed a digital transport adaptor, which came in an esay-to-read self installation kit. Finally after working through the kinks of my do-it-yourself 8 step procedure, i called the "self-help" desk to troubleshoot why the channel "up/down" didn't appear to work. The volume and power button did futher complicating why the channel up/down didn't. Sometimes the most obvious things are right in front of you, but you fail to see it!! Seems like I didn't have the digital box positioned to pick up the signal from the remote!!! Doesn't look to good for me and technology!!! Ha! Ha!
